Hey, all:
I KNOW this has been asked before, recall it was not known, but am curious if it was ever discussed enough to decide if it was silver, aotake, Mitsubishi interior green, or what?? What would YOU use?

Hi Rob,
Yup. Get it while you can! Otherwise, US interior green with some black added will do.

Question for ya'll out there.
Does anyone have any good info on the interior colors of the A5M2a Claude. I was just able to pick up a Fine Molds 48th scale kit of this bird and want to do her some justice. Also what would be the inside cover of the engine cowel.
Looking forward to hearing back from someone (hopefully).
Thanks,
Mark

Mark
This might stir up a hornets nest but I will go out on a limb and suggest that the interior should be Mitsubishi Interior Green. For some good info about this, go to the item entitled "Still Struggling with Interior Colors" in the General section of the FAQs on this site.
As for the interior of the cowl, it probably was aotake when shipped from the factory but I have always approached my cowl interiors as being grimy black since radial engines tend to be very messy in operation.
FWIW

Hi Grant and Mark,
Grant, I fully agree with you as far as the cockpit color is concerned...
Before things really turn wrong for the Japanese at the end of the conflict, each manufacturer used systematically its own interior color in the "living quarters" of planes. It seems to have been a practice that began when the fabric cover disappeared from the cockpit area (I have read that before the general practice was a "clear varnish" on fabric interior giving a strange color through the transparence of the fabric depending on the external finish)...
But I totally disagree with you when it goes to engine cowling interiors. As soon as the use of the so-called antiglare colors (blue black for Mitsubishi, gray black for other manufacturers) came into effect, at least for radial engined planes, it seems that this color was carried into the interior of the cowling, so Aotake which was certainly used as an undercoat was no more visible, even in new planes.
More precisely, on an A5M2 (all variants) which was liable to be in "peacetime" livery or field camouflaged in Kumogata (excepts it seems the latest variant - A5M2 Model 2-2 late)it is almost certain that the blue black was ever present inside the cowling, even when Kumogata was carried over the exterior.
Anyway the practice of carrying the external antiglare color inside the cowling has been demonstrated on existing Zeros both Mitsubishi and Nakajima built ...
Hope it helps.

A5M4 Color opinion needed

Hi to all, 
I'm currently working on Fujimi's Claude A5M4 with tail code W-102.
The problem is when I started to research the color of the plane I realized:
 
1) Fujimi´s instruction state that the color is to be gold mixed with radome tan.
2) In Henry Sakaida´s IJNAF Aces color plate is this plane, I think it was Matsuo Hagiri´s, showed and it is, in my opinion IJNAF light grey. also there's a photo of W-103 with group of pilots in front of it and the color seems to be light grey or NMF.
3) I've been looking at photos of carrier based A5M4 in FAOW#(27?) on Claude over and over again and all I found is that the color of them seems to be light grey or more possible NMF (planes seems to be glossy).
 
I think that light grey color in B&W photo could look the same, NMF could look glossy light grey and if the Gold&Tan color could possibly look like darker grey.
Also most of painted Japanese aircrafts had chipped paint or were totally weathered but photos of claude didn't look like this and that's why I think that they were in NMF or maybe Light grey.
 
But I can be wrong, so if anybody has any suggestion I'll be really glad to read it.

Hi Jan, 
Here we go again !!!
 
Some month ago, we have developed here the subject.
 
David AIKEN sent me (and to some others) a copy of a color slide of an A5M4 Model 4. This slide was greatly altered in color. I have tried to "clean" it as far as I can using a general correction process through Photoshop (I mean I didn't try to get a particular zone balanced). The result clearly let see a tan color on the fuselage despite the fact the propeller hub was clearly NMF...
 
All well exposed black and white photos, including one depicting both Zeros and Claudes Model 4 on the same base, under the same lighting conditions, clearly
demonstrate the Gray green applied on Zeros was a different shade.
 
B&W photos of Claudes clearly make you see that at least three different finishes were used on these birds of which only one was specially and constantly applied
to Model 4's:
 
One NMF finish concerning all planes from the first operational types but camouflaged ones which is definitely a NMF finish because the different shades of metal
following the panels are clearly discernible. This applies to A5M1 Model 1, A5M2 Model 2-1 early and late, A5M2 Model 2-2 both early and late (these ones
being exactly similar in external shape to the Model 4's).
 
A camouflage finish of Kumogata (cloud like) aspect of dk. green and brown on the upper surface, the under surface remaining NMF (applies to Model 1 and
Model 2-1 both early and late).
 
One finish applying only to Model 4: This one looks like a metallic finish of high gloss aspect when new (the panels are all of the same shade). From the B&W
documents, it is impossible to tell whether it was a silver paint application or any other metallic color.
 
However, following the close examination of David Aiken slide and some witnesses of unfortunately undetermined origin, speaking of "golden" Claudes from the
"Genda Circus"; I'm inclined to think that a high gloss amber coat relatively translucent (like the Aotake varnish but not pigmented) was applied to Model 4's as a
corrosion control coat. This giving the plane a metallic tan appearance specific to Model 4's.
 
I have recently discovered that a B 26 airframe, used in France as a technical training airframe by the mechanics of Air France before being stocked and now
restored for the French Musée de l'air was protected from corrosion by such a golden tan mix !!! ...
 
Remember also that prior the modern resin varnishes, the so-called clear coats were in fact neatly amber in the tin and had a marked tendency to yellow with age
 
Unfortunately there is no positive proof yet of the "varnish on NMF" practice on Claude Model 4's...
 
However, what could be ruled out immediately is NMF (all panels are the same shade) and the Zero gray-green finish which is markedly darker and different even
on the B&W documents. The only alternative to the metallic tan being silver paint ...
 
I hope it helps.

Hello Francois,
I know a lot of the conventional wisdom says that the underside of cloud camoed A5M2s was NMF, but IMHO I'm not so sure. Here is an excerpt from my July
23 post. It will give some of my warped logic.
 
>>I'm getting ready to paint my 1/72 Fujimi A5M2a. I'm planning on doing 4-122 with the cloud pattern green/brown. [I began to research the scheme and here is
some of my thought processes or that lead to my conclusion]
 
1) In FAOW #27 (new series) there is a profile on page 70 and a supporting photo on p.31 of a aluminum or NMF A5M2a with a red tail also coded 4-122. Is this the same 4-122 that sports the camo pattern on p.70 and profiled on page 4 in FAOW 27?
 
2) If so, which scheme came first? My guess is the red tail. Herein I thought it would be really cool to have the plane camoed with the red from the earlier paint
scheme still present on the bottom. However,....
 
3) If the red tail was first, was the red on the tail stripped off or painted over? (For those of you who do not have access to the photos in question, the photo on
page 70 clearly shows that the tail cone is light in color and not red or camo.)
 
4) (Here comes the real thrust of all this) What is the real under-side color of the camo 4-122? Is it NMF? Painted aluminum, or grey (Why grey? read on)
 
The Fujimi instructions state "silver (H8, if I recall correctly)" which I take to be NMF or painted aluminum. Then I started thinking, dangerous in itself, the earlier red tail 4-122 would imply an NMF underside, but the photo on page 70 shows the red on the tail is gone. Did they strip off the paint? if so problem solved! The bottom would be NMF.
 
However, if I was camoing a plane I would probably just paint out the red rather than taking the time to strip it. So is underside NMF with the red painted out in
aluminum? Or.....
 
If you look at the spats in the photo on page 70 and compare it to the photo on page 31, it looks to me that the spats seem a little too uniform in color (disregarding
the oil drips). It may imply that these are painted. If painted, is the underside painted aluminum or grey. The grey comes from the profile on page 4. In it the plane's
underside is grey. (in fact all the green/brown camoed planes in these profiles have a grey underside. This is not a color shift due to printing as there are NMF
profiles and A/C parts, i.e. props, on the same page with grey bottoms.) The bottoms were intentionally grey.<<
 
After reviewing this with several members of my local club, we all concluded that the plane had a painted lower surface. I decided to go with the gray. This is partly
due to the profile and a second photo of 4-122 (sorry, but I don't have the FAOW in front of me for the reference) from the front quarter in which the lower
hionmaru appears to be outlined as in the profile. This implies painted to me that the under side is probably gray. So right or wrong it will be gray.
 
BTW, the Fujimi A5M2 and the line drawing in the FAOW of the A5M2 have the pitot tube on the port (left) wing when it should be on the starboard (right) wing,
as with the other variants. The quarter view mentioned above clearly shows the absence of the pitot on the left wing, so unless this photo was reversed or the plane
had no airspeed indicator, the pitot should be on the other wing.
 
Sorry about the length,
Bill

Hi Bill ,
Bill I have studied a lot of 96 Kansen photos but only looking to photos which are not ever of the best quality without taking into account what is known through
other sources may become very disappointing and misleading.
 
I agree the uncamouflaged red tailed aspect to be the original finish of 96 Kansen. However despite the similar code, it should be difficult to prove the particular
plane in red tail become the same 4-122 under camouflage paint (it could be in fact an entirely different 4-122). But this is a minor point.
 
Let’s now examine in details photos of uncamouflaged Model 1 and Model 2-1. You must take into account the fact that on the contrary to the purely American
way to maintain a highly polished aluminum surface on NMF planes akin to chrome finish, most air forces (and civilian companies) let this surface oxidized
superficially which results in a somewhat mat and grayish surface. In the process on planes that were not built with such exotic metals or alloy or anodized parts like
in the early jet age, the differences in shade between the different panels tend to blend into an almost uniform aspect. However looking at Model Art # 272 photos of 96 Kansens, we have at least two photos that clearly demonstrate the NMF finish. One is a model 1 seen in flight by its underside where the spar revetment appears definitely darker than the rest of the finish and a model 2-1 visibly well used on which you can see each panel and rivets, something you are perfectly unable to see on a similar photo of a Model 4, just under it, which clearly bears the disputed 96 Kansen late scheme. It has been also clearly established by photos and research, including samples of actual planes that the heavyweights in uncamouflaged or Kumogata scheme remained with an unpainted undersurface, which, exposed on the contrary to the flakes on the Kumogata scheme, once protected by the paint seems to be painted with a gray or gray-green color instead of being NMF to a point early researcher made the confusion (Beuschel i.e.).
 
It is true that recovered early instructions for uncamouflaged IJNAF planes specified aluminum dope. But they concerned mainly fabric covered planes at that time
and even those remained clearly in unpainted metal where the fabric was not used and aluminum panels took place. From many photographic evidences, all metallic
planes from Type 96 and 97 years are evidently let in NMF despite the instructions, the only parts remaining silver doped being the fabric covered flying surfaces.
The only exceptions being all metallic seaplanes (Type 97 Flying boat for example) which remained silver painted I assume for a better corrosion control. It is only
with Aichi Type 99 dive bombers and 96 Kansen Model 4 that an interim painted finish which is under debate as far as Model 4 are concerned re-appeared (Type
99 are clearly silver painted and we have material evidence of it, but they look much more mat than the Model 4’s) just before being superseded by the much
controversial gloss gray-green offensive finish...
 
Now comes the red tail question... As it was also used on heavyweight bombers and these machines were proven by material evidence NMF underside the same
red tail problem is applicable...
 
Despite this fact they were without doubt NMF under... So ...
 
We also know that the Kumogata scheme was not applied at factory level. Historically speaking we also know the camouflage was applied when it was discovered
the Chinese resistance was stiffer than expected and the CAF was able to bomb the bases. So this camouflage was done by the unit mechanics under the pressure of war operations.
You can expect in that circumstances that this purely defensive camouflage was applied as faster as possible under primitive conditions (and one photo of the very
4-122 in Model Art # 272 even includes in a distance an uncamouflaged aircraft of the same unit) and whenever possible.
 
You’ll certainly agree with me that it is much easier to paint in these conditions the upper surface only, than to cover the under surface with a coat of paint of doubtful defensive value. The red tail (which in fact included the fuselage tail) is much more easy to treat than you seem to think: the metallic part of the plane concerned was simply treated with one of the powerful paint remover that were (and probably still are) common place in the aviation industry. The fabric covered surfaces, already a painted surface being simply coated once again with paint: camouflage on the upper surface, silver dope elsewhere.
 
By the way both because the time consumed in polishing the NMF under surface and the lack of tactical interest in having shiny under surface in combat environment you can bet at no risk that the thin surface oxidation that is fast to appear on aluminum surfaces exposed to the air was certainly present giving on B&W documents the painted on impression that mislead many other people on heavy bombers.
 
That’s why I have to disagree with your conclusions
 
Friendly.
François

Hello Francois,
Good to have you back! How was your vacation?
 
Concerning the your last post on the color schemes of the A5M2a, much of what you posted is compelling and much of it I agree with as well! However, if I have
learned one thing about Japanese aircraft from this board, it is that the generalizing that can be done for most military aircraft of the period is not as applicable to
Japanese aircraft and can get you into trouble! What is proven about one aircraft does not necessarily transfer to others, same manufacturer or not, and may vary
from different planes in the same unit. As Jim so frequently expounds, the proof is in hard evidence. As far as I know there are no relics from a cloud camouflaged
Type 96, so everything is speculation based on eyewitness accounts and photographic interpretations.
 
I guess my point is that the possibility of the gray exists. All Cloud camo Claudes may not have been the same. Some may have been painted while others left NMF.
There are examples of shipboard cloud camoed planes that had a gray underside (at least I don’t believe there is any controversy that these were gray). These are
the float planes (Dave, Alf, etc.). Agreed, these planes required the corrosion protection and let’s not get into a chicken/egg discussion as to which planes camo
came first (unless it shows a flaw in my logic). These aircraft coexisted. The A5M’s, as well as their maintenance crews, were most likely carrier (or ship) based at
some point. So, it stands to reason that the experience for the camo pattern painting was transferred. They may have painted these planes the same way. The
bomber maintenance crews, on the other hand, were most likely not ship based and would not have had this experience. (Granted, my knowledge of JNAF
organization is pretty slim.) All of this is speculation, but no more so than the speculation of stripped red paint.
 
Perusing the references late last night, something struck me (before my wife’s thrown book) in the photos of 4-122. On the rear, fuselage where the ID plate is
located is a light colored box. This is probably where the serial number was masked during the painting (see the photo on page 143 of MA510 for a close-up of a
similar painted-out/masked ID block on an A5M4). No matter which aspect or printing of the photos of 4-122 I look at this block contrasts the underside color
directly below it and on the tail cone. If the block is the masked serial number than its background should be NMF, than the underside color is probably not NMF,
oxidized or not, as the two should have oxidized equally. This is also evidenced by the A5M4 on the MA510, P.143 photo. The underside color is definitely
different as the masked block and underside colors are in contact. This machine also appears to have a cloud camouflage.
 
Nohara, in MA510, p.128 indicates that 4-122 had a D2 (green) and H2 (brown) upper camo pattern and a J3 underside. However, he does place a question mark by the J3. I cannot read Japanese so I have missed his exact intent of the comment. (any help with this caption and related info from MA510 would be appreciated from the Japanese literate, TIA) So, the possibility also appears to exist with him, as well.
 
Overall, I am not saying that the underside was gray, but rather that the possibility exists that it was gray. I don’t think we will ever get conclusive evidence from the
photos as all evidence is circumstantial.
 
Best regards,
Bill

Well Bill, Though I must agree to the fact that generalization might be perilous for Pacific wartime aircraft camouflage (though it seems to be even truer for Army
planes than for Navy ones), I’m much more confident for the pre-Pacific war period that the military establishment of Japan (like any other in the world) was issuing
regulations to be strictly observed and that the circumstances permitted them to be relatively well complied with. We had a discussion face to face Jim and I in late
July in Paris. We agreed that ONLY HARD (material) EVIDENCES are SCIENTIFICALLY receivable as evidences. However, the modeler, who must complete a kit as something “as accurate as it might be” but has no hard evidence on everything he needs to do so must use the “best educated guess” he can or stop modeling ! ... So he must resort on logic and to the examination of current practices where they are known for sure to produce what is not an exact duplication of the real thing at reduced scale (the inaccessible dream of the modeler) but what could be considered as the most believable reproduction he can considering what documents are available (do you know exactly how 4-122 looked the other side of in plan view ?). In fact it is “believability” vs. total accuracy ...
 
>I guess my point is that the possibility of the gray exists. All Cloud camo Claudes may not have been the same. >Some may have been painted while others left
NMF.
 
True, but there are no convincing photographic evidence of that and every piece of knowledge we have available and logic tend to consider this is not the most
believable situation...
 
>There are examples of shipboard cloud camoed planes that had a gray underside (at least I don’t believe there is >any controversy that these were gray).
 
From what sources is based this affirmation? Though Some Type 97 Model 3 Torpedo bombers most probably did use the same colors as what I call a last thought camouflage during Pearl Harbor on some carriers, it was not the same pattern and if David Aiken sent me a pic of a Kate underside proving the use of some kind of undersurface color (also directly applied on NMF without primer) this was not related to these planes and nothing indicates that all “Hawaiian Operation” Kates were so painted underside (and even painted there at all)
 
>These are the float planes (Dave, Alf, etc.).
 
Again from what sources do you take this information ? True they were painted underside but silver, not gray, unless you rely on some color profiles of dubious
historical value. Beside those camouflaged floatplanes were temporarily detached from their mother ships to shore base during the China War ...
 
>Agreed, these planes required the corrosion protection and let’s not get into a chicken/egg discussion as to which >planes camo came first (unless it shows a flaw in my logic)...
 
It seems to have been E8N floatplanes but nothing’s sure here ...

Not all, We have few images of camouflaged 96 Kansen coming directly from a carrier (though I have located at least one source) on the contrary to dive bombers
and torpedo-level bombers planes. Most of the 96 Kansen Model 2-1 were from shore based Kokutai and based on roughly equipped ex-Chinese airfields...
Maintenance crews were as far as I know part of the Ku. Itself and many might have never sailed on a ship ...
 
By the way, during the early part of 1942 stripping the red tail paint (and most probably repainting on fabric covered flying surfaces) was common place on 96
Kansen Model 4’s still engaged in war operations (many photographic evidences here).

It is a constant Mitsubishi practice that lasted into the Zero production to the end of the war (though in the Zero case it was on the gray-green) to let the id. plate on
a single color background (on the contrary to Nakajima produced birds). I have compared last night on MA 272 (I have not yet secured MA 510) the gray
rendition of this plate (on B&W photo) to the gray rendition of the fuselage tail cone of 4-122. Considering their relative placement from the light source there is NO SIGNIFICANT DIFFERENCE that could be extracted that proves without doubt the rectangular zone behind the data is finished an other way than the underside of the plane (remember that the main differences in shade on a B&W photo result from light contrasts not from surface colors). This proves or disproves NOTHING at all....
 
>Nohara, in MA510, p.128 indicates that 4-122 had a D2 (green) and H2 (brown) upper camo pattern and a J3 >underside.
 
Sorry Bill but after being an enthusiast Nohara’s theories supporter, the last year on this board has convinced me that he can err like any other researcher...
 
> However, he does place a question mark by the J3.
 
I still think the most probable option is that NMF was retained underside as nothing to this days proves any interest of IJNAF for any kind of ground to sky
camouflage before the Zero inaugurated a totally new approach of purely offensive camouflage. We may even legitimately consider that camouflage itself was
considered a liability to be dispensed with as soon as possible as IJNAF authorities reverted to their “peacetime” high visibility finish as soon as air supremacy
became a reality at least on newer planes (but the heavies). I am up to a point that I consider IJNAF authorities to have no theory on camouflage but one on
defensive purpose on the ground or during low altitude operations (or escape) over land until the offensive camo of the Zero was developed. It is also important to
notice that a sea camouflage was “panic developed” only during the early stages of the Pacific War (the Zero fighters excluded) and not generalized to all models and codified for all planes before at least June 1943. In this context I see no reason why the 96 Kansen or any other planes during the China War should have received an undersurface camo at all. Notice also that except for the B5N’s the gray green (of all variations it could have been) used on undersurfaces was originally the original all over offensive color and that only the upper surface was altered to provide a sea camouflage but - as hard evidences are concerned - on a Type 99 dive bomber quoted by Jim as using silver paint there. As many of these planes were used on the reserve force in their pre-war red tailed + silver paint finish, and considering many planes from the reserve were dispatched to the Solomons front in a hurry during the period this plane was shot down, I will guess almost without risk its upper surface (in green from hard evidences) was the only part of the plane reconditioned to make it go to war as a replacement. A demonstration that even in 1942 the attention to undersurface aspect was still considered a minor preoccupation...

You write:
 
"By the way, during the early part of 1942 stripping the red tail paint (and most probably repainting on fabric covered flying surfaces) was common place on 96
Kansen Model 4’s still engaged in war operations (many photographic evidences here)."
 
Well, I do not wish to stir controversy, but according to Mitsubishi production records the A5M4 continued to be produced at the plant alongside the A6M2
production (as follows):
 
1940
 
Ja 20/1 (first number is A5M4 production, second number is A6M2 production)
Fe 19/1
Ma 17/1
Ap 14/1
My 14/4
Ju 14/3
Jl 14/9
Au 6/8
Se 5/9
Oc 11/19
No 9/23
De 10/19
 
Total A5M4 production for 1940 = 153; Total A6M2 = 98
 
This fact originally lead me to question the reason for Mitsubishi to continue painting the aluminum paint on the Claude while painting the Zeros in gray-green.
 
I would also like to propose that the factory and/or field application of the red tails to Claudes stopped at during this time period as well. We do not see any
evidence that there were red-tailed Zeros. So, I must respectfully disagree with you that the red tails were "stripped" off the late production Claudes. I do not believe
they were ever applied!
 
It was this reasoning which led me down the path with the possibility that late model Claudes may also have been painted gray green like the Zeros. I just cannot
fathom the Mitsubishi factory running simultaneous production lines and painting the two types of aircraft in a different scheme!

Jim, I reviewed the Zero production figures of Mitsubishi in Mikesh’s book last night.
 
The first Model 21’s were produced during November 1940.
 
As we have ample photo evidences (despite we still don’t know for sure the colors) that most (if not all) Model 11’s were two toned, it is legitimate to consider that their scheme was not the definitive one of gray green all over but that these aircraft were most probably used as camouflage test beds. Beside, the Model 11’s were produced in very limited number and this Model is more akin a pre-series than a mass production. As the Zero fighter was the first aircraft in the IJNAF to bear the new “offensive” camouflage which (with all color variant related to manufacturer and even aircraft type) was to become an IJNAF early Pacific war standard, we cannot expect Mitsubishi to order large quantity of the new finish BEFORE IT WAS OFFICIALLY DEFINED AND STANDARDIZED. On the contrary the Claude line, which was to close only one month after the first Model 21’s with the new standard finish was to begin to be mass produced, things were yet in a mass production procedure and the finish used (whatever it was in fact) was a standard for the manufacturer and ample quantities of this finish ordered before were certainly at hand and available. So it is entirely logical in my opinion that Mitsubishi produced the last Claudes in the finish they originally began to proceed with since the Model 4 entered production.
 
We must face the fact that not a single photographic evidence exists that any Claude used as a combatant aircraft was finished the same way the Zero was. On the
contrary, a photo exists of late Claudes and Reisens staying under the same light conditions on the same apron, the Claudes being WITHOUT red tails, that clearly
demonstrates the finishes were different. I think we cannot do otherwise than admit a kind of interim finish was carried by Claudes between the NMF or
camouflaged period and the new gray green finish was applied on Zeros. Another kind of interim finish was carried by Type 99 Dive bombers which despite being all metal aircraft clearly appear as silver painted (but not so glossy as the Claudes) on photos. Earlier, all metal planes (Type 97 Torpedo planes or heavies, early
Claude models) were clearly not painted at all when not camouflaged (but the red tail if carried). My opinion is that from Model 99 on and before the new gray
green became a standard, a corrosion control problem led the IJNAF authorities to order the all metal plane to receive some kind of corrosion protective coat.
Concerning the Claudes, I think from what I have seen on David’s slide after applying global corrections with Photoshop that the most probable color of this finish
was a light golden tan with some metallic aspect, though the silver paint (of a glossy variant) is still a possibility. I still believe that the most probable way to apply
such a golden metallic tan finish is the use of a translucent amber varnish and applying translucent varnish for corrosion control was still a common Japanese practice
(though in that case using blue or green pigments FOR CONTROL PURPOSE) which has a name: Aotake. Notice also that the old Model Art 272 translation I
have spoke about inconvenience of silver paint as not controlling perfectly the corrosion process because it contained aluminum particles itself...
 
Concerning red tails you will see my commentaries further in the text
 
>>David
You write:
"the first presentation of aircraft from the factory without the red tail was at Haneda Airport on 21 March 1941."
This is very interesting that the Mitsubishi factory may still have been producing Claudes in 1941, but this is unlikely. According to the Mitsubishi Heavy Industries,
Ltd., Corporation Report No. 1, as compiled by the USSBS, page 124, the last 10 A5M Claudes were produced by Mitsubishi during December 1940.
If both of the previous statements are facts, than Francois is correct! The Japanese officials must have taken some Claudes from one of the units, stripped the red
paint off the tails, and made presentation aircraft out of them. Then sent one to the Akagi and reapplied the red tail! << ...
 
I have noticed a strange correspondence in the delays between the following facts:
Last 96 Kansen produced: Dec 1940, mentioned Haikoku ceremony March 1941
First Nakajima built Zero 21: Dec. 1941, first of these planes seen in front line units: spring 1942.
 
It seems that about three months elapsed between an airframe is produced and the time it reaches the units (when the usual pipeline is used and no “operational tests
carried of course).
 
Concerning the red tails, I think there was not a single date to proceed with their elimination.
 
Not a single plane from the first fleet carriers carried them (but - may be remnants - on some Kates rudder and fins under the codes tat might account for the specific color of the fin on some otherwise green upper surface painted planes). On the contrary, the reserve force, including the third carrier division (this one having an horizontal red stripes on both fuselage sides) seems to have carried the red tails even up to Doolittle raid... You once told me the Ryujo Claudes operating over the Philippines in Dec 1941 were depicted on a painting as carrying them... And all Model 99 planes operating over China until the withdrawal of the IJNAF from this theatre in 1941 seems to have carried them but the very late deliveries (in gray green). On the contrary, a photo of a pranged Claude in the Marshalls in 1942 clearly shows the absence of red tail (despite the finish is clearly not the gray-green). Would it be surprising that from the time it was determined that aircraft destined to operate as first line combatants were to be dispensed of red tails and those in reserve should keep it the earlier procedure of applying the red tail in the factory should have been discarded as it was not known to which kind of units the newly produced plane was destined to ?
 
Finally I think both red tail removal AND red tail not applied existed. When a plane carrying the factory applied red tail went to a front line unit, this red tail was
removed. When a plane from a batch factory produced without red tail went to a second line unit, the red tail was painted (even when they went to a first fleet carrier unit as it was already known they were to be replaced by Zero fighters), when they went directly to a first line unit, the code was directly painted on the factory finish
...
 
The real problem is to determine the date red tail became an option and the date it was definitively eliminated...

Thank you Francois for your input and feedback.
 
I suppose the best we can say is:
 
1)Red tails existed on IJN aircraft from the mid 1930's until the mid-1941 as an official practice.
 
2)Some units continued to have (apply) red tails until early 1942.
 
3)We have no direct evidence that the red tails were applied at the factory (or do we?).
 
4)Zeros never carried red tails as an official marking.
 
Now, what we need are copies of any official orders documenting the exact dates instituting these practices. We know from other documentary evidence that there
was often a gap in time before an official order (probably verbal) was given and the formal adoption of the practice by the Kaigun Koku Honbu and its publication in the Nairei Teiyo (Manual of Military Secret Orders).
 
I have several editions of the translated Nairei Teiyo. However, I have yet to find this important information regarding red tails. I do know when the official orders
were given to increase or decrease the official size (measured in aircraft per tai) of the various types of hikotai beginning with the year 1936. I have also found the
date of the joint Rikugun-Kaigun agreement abolishing the hinomaru on the fuselage of army planes (but not the date the orders were given to reapply the hinomaru
on army planes!). These documents are not complete.
 
Oh well, continued digging in the various archives may yield the information we need!

In Response To: Red-tailed Mystery! (James F. Lansdale)
 
Hello Jim, 
Sorry for being a bit late to answer...
 
I agree with your summary and your wishes except point 3.
 
I have a picture of a 96 Kansen Model 4 sporting no unit ID, no Aikoku markings but a red tail which is really brand new from what could be seen on the picture...
 
So I suspect that red tail application by the factory as a standard marking was a current practice until it was discarded at an unknown date because red tails were no more standard markings for all units, those units still using them becoming reponsible for their application (and those units no more using them being responsible for their elimination whenever they still have older red tailed planes in inventory by the way)...
 
Unfortunately we have but very few of the markings and camouflage instructions still available (in contrast with those of the USN or the USAAF)for consultation.
 
However I do not despair of seeing some surface one day from an old pile of files recollected by the US, British or Australian authorities stocked in some remote
locker and long forgotten (and perhaps never studied at all)... Or from some private collection here or there including Japan ...
 
At least we can hope for that I think :)))
 
Friendly.

Aloha All,
In the 18 June 1998 posting (on this website) titled "Hokoku presentation aircraft", it was stated that the first presentation of aircraft from the factory without the red
tail was at Haneda Airport on 21 March 1941. See the famous shot of Hokoku #378, in Thorpe & Model Art, taken that day. One of these "presented" aircraft,
Hokoku #422, was noted in that post, as later serving on the AKAGI in the summer of 1941 WITH a red tail. This shows application in the "squadron level" in the
summer of 1941.
 
Of interest, the first "presentation" of a Zero was Hokoku #433 on 8 Nov 1941 at Haneda Airport.
Cheers,
David_Aiken

Aireview's Japanese Navy Aircraft in the Pacific War has a table of aero engine statistics, but does not cover the Kotobuki.
Aireview's Japanese Army Aircraft of the Pacific War has a similar table, including the Ha-1, which I believe was the IJAAF version of the Kotobuki.
Details given there are:

These might be figures for a later model Kotobuki.

In Response To: A5M4 CLAUDE (Bob/Texas)
 
Dear Bob,
The "golden look" of the Model 4's is to this date speculative, it might have been a high gloss aluminum paint too, though I believe the varnished bare metal is entirely possible (and probably more likely) too.
As far as combat units are concerned, the only variation of the finish of Model 4"s that is recorded by available material is the disappearance of the red tail probably from early spring 1942 on when the aircraft were actually engaged in combat. Although second line units might well have kept theirs longer...
Later, when some Model 4's were used by training units at home, it seems some were repainted following the current scheme used by fighters after June 1943, though the actual undersurface color is unsure, Model Art 510 authors go for the usual gray-green (in that case which one ?) and personally I think more probable the undersurfaces remained what they were before the application of uppersurface dark. green.
The Kumogata scheme you refer to, seems to have been discarded for use on fighter planes (and much other types excepts transports and heavy bombers) from sometimes in 1939 in China (though a lot of planes already painted so remained in the scheme later and even at the beginning of the Pacific war, but this mainly concerned fabric covered oldies for obvious reason I won't detail their).
The last Claude version to have been painted in Kumogata scheme seems to have been the Model 2-2 early variants (those with enclosed cockpits). Later Model 2-2's (externally similar to Model 4's)seems to have reverted to the original bare metal scheme with red tail of the "peacetime livery". Model 4's on the contrary looks clearly different with no discernible different panel shades and a high gloss (when new) aspect. Interestingly enough when the Aichi D3A1 were introduced almost at the same time in frontline service, on the contrary to their bare metal prototype, they were clearly covered by some kind of aluminum dope (though semi-matte on the pictures like the contemporary finish of metallic flying boats)with red tails. I think some kind of protective anti-corrosion finish has been required by the IJNAF (most probably in mid or late 1939) following the apparition of intergranular corrosion problems on shipboard bare metal planes, despite the use of Alclad treatment... As the finish was different for D3A1's and Model 4's, I think the respective manufacturers used some stop gap makeshift solution of a different nature. As Aichi was already producing floatplanes during this period, I think they just used the already available dope, while Mitsubishi resorted to another "off the shelves" trick.
If the use of varnish is confirmed by hard evidence one day on Model 4's I won't be surprised if we discover a thick application of the same base once used for Aotake internal anti-corrosion finish which was at hand available in quantity and a proven anti-corrosion mean (remember that Aotake was a varnish as clear as the knowledge of the time will allow which was simply colored by pigments in green or blue for application control purpose and as prone to yellow as other so-called clear varnishes of the time).

Would the varnish coating be applied at the manufacturer, or at the squad level? Basically would all squad , and national marking be overcoated with that amber varnish,or not?

In Response To: Re: Claudes (MDriskill)
 
Hi Mike
The Western origin of references to clear coating (or the so-called "amber varnish") occurred in Volume IV of "Aircraft of the Fighting Powers" published in 1943. In the Japanese section of the "Compendium of International Military Aircraft Markings [and] Regulation Colour Schemes" appears an interesting mixture of information as follows.
"International markings: A red disc painted above and below the wing tips and on the fuselage sides of both Army and Navy aeroplanes. On camouflaged surfaces the red disc is outlined in white. Many differing camouflage schemes have been tried on Japanese aeroplanes and some have been finished in a clear lacquer (sic) so as to reflect the natural surroundings. The upper surfaces are camouflaged in tints of grey, purple, and green, while the lower surfaces are pale grey. Other machines have been painted pale grey or pale green on both upper and lower surfaces. Unit markings take the form of white horizontal bands of varying thickness across the vertical tail surfaces and vertical bands surrounding the rear fuselage." (AFP, Vol. IV; p.LII)
Commentary: While most of the material cited is generally accurate in spite of the use of generic color descriptions, the most interesting statement herein is the alleged application by the Japanese of "a clear lacquer so as to reflect the natural surroundings." This citation provides the first published record of a so-called clear coat on Japanese aircraft. Research and examination of scores of relics since the time of this publication have failed to support this contention. In fact, the Japanese Naval Test and Research Center at Yokosuka had come to a much different conclusion as early as February 1942. In the "Yokosuka kokutai official report No. 0266, "Research of Camouflage For the Type 0 Carrier Fighter," the writer of the report stated an opposite finding:
"1. The effectiveness of camouflage by the application of various colors differs greatly and is dependent on the background. Therefore, it is difficult for just one color to fit any kind of situation.
2. It is easy to spot aircraft without paint because the reflection of light on the metal [may be seen] at a great distance. If one renders the surface lusterless, one can reduce this weak point no matter what color is applied."
(Yokosuka Kokutai Report No. 0266; p. 2)
Thus, if a clear coat were to be applied and contribute an effective camouflage it would need to be transparent yet not shiny nor made "to reflect the natural surroundings" much like a mirror! However, the assertion that a clear coat had been applied by the Japanese to their aircraft was erroneously repeated:
"The usual camouflage markings are carried by the OB-01 [Mitsubishi G4M Betty] and it is reported that certain of them have been finished in clear lacquer so as to reflect the surroundings in which they are operating." AFP, Vol. IV; p.75.
Commentary: One possible explanation for the shine reportedly observed on the Betty land-based naval bombers is that the glint may have been the result of light reflection on the unpainted lower surfaces of the aircraft or it was the reflection from a paint scheme which had not been rendered "lusterless." Again, it must be emphasized that the reflection of light by the application of a "clear lacquer" would have been the antithesis to the purpose of camouflage and certainly unnecessary if the surface paint were glossy when applied. There would have been no purpose to apply a clear coat to an already shiny surface other than to protect an otherwise bare metal. A flat opaque coat of paint would have been equally effective in protecting the surface and serving as camouflage. In the event, it is extremely difficult to determine if light reflection from a surface is due to the application of a clear coat by merely observing it. One would have to physically examine the painted surface in question layer by layer to make a definitive determination.
I hope this clarifies this issue for our MB members.

Dear Mr. David Aiken,
Thank you for your e-mail. Just found the thread between Francois and Jim on "j-aircraft". Jim wants to know what Aireview issue the "Ameiro" on the A5M4 was first cited. It was in issue #289 September 1971. Is there anything in the text to help resolve the "Ameiro" problem?<
Yes, I knew 9/71 issue of Aireview. There are five vanish coated Claudes in sixteen profile drawings, which are 9-151, 9-158 (Hokoku-278), 9-137 (Hokoku-317) of 14 Ku,1940 and VII-111 (Hokoku-348), VII-119 (Hokoku-386) of Soryu, 1941. The illustrator, WATANABE, Rikyu stated that Almite color of upper five Claudes might be standard for Claude painting. These were painted silver first, then over-coated vanish which looked like Almite color of lunch box. I had a telephone call to WATANABE, Rikyu to reconfirm its background a month ago. He got this information from IZAWA, Yasuho who interviewed someone (Mr.WATANABE did not remember his name) who stated vanish coat over silver paint because silver paint was not so tough touchness with seeing of his Hokoku Claude photogragh. Mr.WATANABE had never say for salt air corrosion control.
HASHIMOTO, Kikuo copied profile drawings of VII-119, VII-111,9-151 of Almite Claudes on 4/76 issue of Koku Fan. In 1986,NOHARA, Shigeru wrote vanish coat was painted against salt air corrosion and it was Claude's standard painting since 1939 in his caption of MA#272 Navy fighter special. NOHARA has a lot of errors since his debut of Maru Mechanic #14 Zero special. He wrote vanish coat Zero for explaining Ameiro in FAOW#9 without permission, but which was suggested by OHTA, Masashi. I have a great question why vanish is painted on the metal paint or natural metal. Varnish is for wood parts or component only.
My friend, ASANO, Masaru does not believe varnish coated Claude or Zero and me too.

The "Aircraft of the Fighting Powers" books were published during the war and were the best that could be done at the time in view of the fact that, unlike the enlightened days in which we now live, there was NO co-operation at that time, from the Japanese side !
Drawings were often inaccurate by present day standards and the B5N, surely a major type, was not even covered.
I therfore feel that comments about colour schemes in these books should be taken with a grain or two, of salt.
Nevertheless, they remain among my fondest possesions.
Aircraft aluminium is quickly corroded by sea water and we are talking about Naval aircraft. Alclad which has a corrosion resistant surface, was widely used for sea operating aircraft but whether this was used on the Claude,
I do not know. Varnish seems quite probable.

Dear Friends,
I noted one remark in this message about varnish being only for wood products.
Not so. Most Japanese paints of WWII were varnishes with pigments or dyes added for color. Japan had mostly real varnishes because the country had an ample supply of the raw materials needed to make varnishes.

Subject: "Golden" Claudes/Update
Date: Sun, 2 Jan 2000 17:24:56 EST
Dear Dave,
Spoke to my father yesterday to wish him Happy New Year and got the low down on his eye-witness to "golden" Claudes. I had asked him to think about it and do some digging for me when I called him at Christmas, and gave him a week to chew on it. He just turned 79, but is in good health (knock on wood) and his mind is perfectly clear, so we need give no more than the usual allowance for the fallability of human memory that we would give to anyone.
First, however, a little background. As I am sure you are aware, there is reference to the "Nisu" overcoat on Claudes in Bunrindo's Famous Airplanes of the World No. 27 (March 1991) on the Type 96 Carrier Fighter. Most of this book was put together by Kazuhiko Osuo. At p. 67, under the section on "Type 96 Kansen Camouflage and Markings", he says: "actually, the overall silver dope finish was the only basic finish which the Type 96 Kansen had, the brown/green "kumogata" finish seen on aircraft of 12--15 Ku during the early years of the China Incident being no more than a temporary scheme. The procedure adopted in 1939 (Showa 14) of applying a coat of surface preservative ("Nisu") over the silver dope finish on carrier based aircraft as an anti-corrosion measure did cause considerable change in the surface color, and thus, technically, should be distinguished. Almost all Mark 4 Kansen (i.e. A5M4) were in this latter finish." Again, Osuo gives no primary source, but he is a diligent and respected historian/researcher and here we have another source for this phenomenon aside from the Izawa/Rikyu Watanabe line of inquiry.
Now for the details of my father, Yoshio Tagaya's comments to me yesterday. You will see from it that, contrary to Osuo's text in FAOW No. 27, we appear to have evidence that the "Nisu"-coated finish predates Osuo's 1939 date by a considerable margin. The "Air Show" in question took place on Saturday, June 5, 1937 at Haneda Airport, Tokyo from 8:30 a.m. until 2:30 p.m
