Unusual Ki-45 Toryu

on page 115 of Model Art 329 (Army Fighters, 1989) there is a b/w illustration by Hasegawa Ichiro san of a very unusual Ki-45. The photo caption reads:
"Upper surface Natural Metal Finish, lower surfaces kuroi (black), Model Hei belonging to the 5th Sentai, Showa 20 (1945) (can't read the name of the base).
In order to improve wind resistance and climbing characteristics the paint of the upper surfaces together with the radio mast were removed from this plane. Nose and rudder were painted red with the marking and the "letters" in white."
 
Maki Koichi san repeats the same in the photo caption of page 52 of the old blue cover FAOW (No.26, June 1972). NMF upper, Black lower.
 
Nohara Shigeru san folows with a color profile of the plane on pages 61, 62 of the old Maru Mechanic, No.11, 1978. As above, upper surfaces are depicted as NMF, lower as Black.
 
Nevertheless, on page 49 of FAOW 21 (1990) Nohara san says that the plane was painted ANKASHOKU (Dark Brown) overall, then the paint of the upper surfaces was removed. The reason was that the plane belonged to Sentaicho Yamashita Yoshiaki and he wanted his plane to be easily recognizable in the air. But since it wasn't really camouflaged that way there were complaints from high ranking officers. He also mentions that as can be seen from the photos at page 48, there were more planes with similar paint scheme (middle of upper photo, first plane from the right lower photo) and they belonged to the Sentai Hombu (H/Q).
 
What I see is that the engine nacelles (FAOW 21, p.49, upper photo) are painted in a much brighter color than the underside of the fuselage. Could it be that the fuselage underside was painted Black while the nacelles were left in their Dark Brown?
In the bottom photo of the same book, I can barely see some color difference between the nacelle and the rest of the wing but in the middle photo the wing root looks a lot darker than the rest of the wing. Could it be because of the angle of the light in the middle photo or both the upper and lower surfaces of the wing were left in their Red Brown scheme?

As you may remember, I intend to do one of the two Ki-45 models you sent me in this unique scheme. Besides the references you mention, there is also a color art profile in MM#44 that shows this a/c as NMF upper and black lower. Nohara san may claim that the color was dark brown, but I'm sure that is merely conjecture. While I wish it was NMF with black underside, because that would look very cool, my conjecture is that the lower side is most likely dark green with the top side stripped to NMF.
 
I don't think that there were several a/c in this scheme. I believe that the Nick in the top photo on p 48 (FAOW 21) is the same a/c as the one pictured on p 49.
 
I also have my doubts that the Nick in the lower photo on p 48 is another Ki-45 in the same scheme. I wonder if it isn't the same Nick shown on the bottom of p 45 (both have their starboard side engine cowling off for repair).
 
I believe that the dark wing root fairing is a trick of the light, and that the nacelles in the top photo p 49 are not actually a lighter color but just reflecting the sun light.
 
That the paint was stripped to improve performance is plausible; reduces both weight and drag. But it makes more sense to me that this may have been done for recognizability. After all, this is a rather loud and dramatic scheme to be called camouflage. As for the antenna mast being removed, the antenna masts have been removed from all the 5 F Nicks in that group.
 
Of course, all of this is just armchair speculation on my part.

VERY interesting subject this one!!! Personnally, I think that the painting instructions in Hasegawa´s Toryu kit CP4 aren´t that far off - just the upper side of the fuselage is shown as nmf here, the upper surfaces of the wing remain in the same "Kawasaki Green" as the bottom of the plane.
All illustration of 5. Sentai Toryus of this vintage I´ve seen so far show them in the "Dark Olive Green" scheme, not the red-brown we often see on the illustrations of planes operated by the 27. Sentai in the Philippines for example.
The reasoning for this is unknown to me, supposedly this is based on the recollections of surviving veteras of the unit - the 5. Sentai apparrently suffered very few losses during their home defence operations.
Anyway, the dark wing root suggests that the upper surface of the wings were left in the factory scheme as well, the reflective properties of the "cleaned" upper fuselage would suffice to provide immediate recognition in the air, I suppose.
I don´t really give too much on the tonal values of monochrome photos anymore, too much depends on the type of film, exposure, lighting conditions etc. to deduce the actual colour from such photos.
But to me it doesn´t seem to make sense to strip the original paint from the whole airframe and then repaint the bottom in black, let alone overpaint the previous camouflage colour in another layer of black that would add even more weight to the airframe.
Oh, and please do note the "thin wire" antenna arrangement on the plane in the upper photo on page 48, remember the Ki-46 in China, George?!?
While I do like the idea of the nose and rudder being red I somehow think they were simply left in the previous green colour again.

Like you, I agree that the painting instructions of Hasegawa´s Toryu kit CP4 aren´t that far off. But I don't agree with their notion that the top side of the wings were left dark olive green. I draw my conclusion from the fact that the tops of the horizontal stabilizers were stripped to NMF like the fuselage. And in the bottom photo on page 49 (FAOW#21), I can see the demarcation between the NMF and the darker painted area around the top of the nacelle.
 
You wrote:
"the dark wing root suggests that the upper surface of the wings were left in the factory scheme as well."
 
That was my original thought too, and this photographic detail does pose a conundrum. Also, I'm sure this is the detail that tipped the scales for the folks at Hasegawa to call for the wing tops to be painted green. But again, I think this is merely a trick of the light. The photo that shows the wing root as dark is a distant shot of the port side, while another photo that is a very close shot of the starboard side wing root appears to show a NMF. Of course it seems highly unlikely that the port wing would be painted while the starboard wing was NMF. So I conclude that the dark wing root is a lighting fluke in that particular shot.
 
I agree totally that confirming tonal values from monochrome photos is too unreliable, if not down right impossible, due to all the factors involved. I know of b&w photos that make yellow IFF look almost black, and darkly painted a/c that look like NMF, and Hinomarus on a particular a/c appear black in one shot while appearing almost white in the next shot. Extreme apparent variations caused by no more than the angle of the light from one shot to the other.

I think you have a valid point here. But then, the Japanese didn't seem to have a problem with the idea of adding weight to their a/c because of overpainting. They often overpainted; and often laid it on very thick and sloppy. But if you were going to strip an entire a/c and then repaint any of it, painting the bottom would be the biggest pain in the a**. Personally, I think that just leaving the bottom in the original dark olive green makes the most sense. Especially when one considers that stripping the bottom of the a/c (like painting) would be twice as hard as stripping the top side. (Have you ever had to strip, paint, or repair a ceiling? Man, that sucks!)
 
You wrote:
"While I do like the idea of the nose and rudder being red I somehow think they were simply left in the previous green colour again."
 
This too makes sense to me. But then (and I know that this flies in the face of what I wrote above about inferring color from these old b&w's) There does seem to be a tonal difference between the lower color and the rudder color, while the rudder color appears to be exactly the same as the Hinomarus in all the photos. Also, the nose and rudder would be the easiest and the most likely areas to paint if you were going to add red. And if the point was to be noticeable... Well, this scheme is that.

let me try to disagree with you in order to search for the truth.
Maybe the Dark Brown of Nohara san is a conjecture. Why do you say that the color is Dark Green? On what do you base your conjecture?
The plane in the top photo of page 48 is too small to judge (those who have examined the actual photo may know better) but I see that its rudder doesn't appear to be red and that there are planes parked around it that don't appear in the photos of p.49.
I don't know about the plane appearing in the lower photo of p.48.
Regarding "the nacelles...reflecting the sun light" in the top photo of p.49. Please notice the shadow of the propeler on the right nacelle meaning that the sun must have been somewhere above and to the front of the plane. But also notice that the right nacelle is lit while the left nacelle is in shade. This means that the sun is to the front and right side of the plane. But if the sun was positioned like that I don't understand why the nacelle looks so bright while the undersides of the fuselage look so dark.
Furtheremore, the color of the nacelles looks closer to the Hinomaru than the underside of the fuselage. If the nacelles are dark green and look so bright because of the sun light, then the Hinomaru would look a lot brighter, wouldn't it.
Compare also the color of the right nacelle to the color of the propeler and spinner.
I'm toying with the sun position and the shades here, I know. Your thoughts?
 
I believe too that the plane was stripped to make it more easily recognizable.
Yes, all planes have their radio masts removed. It was a translation mistake in my part. As I have told you long time ago, there is no "-s" to indicate the plural form in the Japanese language. So "hikoki" might mean one or a lot of airplanes. Therefore my mistake. Sorry.

Joern responded before I got the chance, and he answered pretty much as I would have. (I'll respond to Joern's post seperately). It's fun to speculate, and that's all my following responses are...
 
You wrote:

The same thing as Nohara san; personal opinion. Well, that and the fact that dark olive green appears to have been a far more common color for Nicks. So I'm going with the odds and my gut instinct.

Because the sun is almost directly above the a/c and the bottom is in shadow.

In which photo? It varies from photo to photo.

Not necessarily. I agree with Joern, that one cannot verify conclusions about color from monochrome photos for all the reasons he sites. I have seen too many photos of dark colored a/c that look like light colored a/c because of a trick of the light on the old films.
 
Compare also the color of the right nacelle to the color of the propeller and spinner.
 
To me, this just confirms my original observations.

There is a colour photo of an anonymous Nick at Clark Field on page 135 of Pacific War Eagles.
 
This Nick is in good condition and the colour looks more like an olive drab. It's not really a green per se when one compares the airframe to the grass surrounding it. I guess some folks would see this "muddy colour" as a "brownish-green" whilst others might see it as a "greenish-brown"!
 
Wear around the wing roots seems to expose a grey - (hairyokushoku?) - and then nm. The rear face of the prop blades can be seen as a definite brown in comparison to the "greyish" olive drab colour.

of course it's very difficult, almost impossible to draw conclusions from B/W photos. We all agree with this. Nevertheless we try to.
I'm refering to the photo of FAOW21, p.49, top.
I repeat again that the color of the right nacelle (and a bit of the left) is closer to the Hinomaru, the propeller and spinner and the nose, making it a much brighter color than the undersides of the fuselage.
I repeat again that if the sun was so bright as to make the nacelle, painted like the undersides, to look so brighter, then the Hinomaru would look a lot brighter too....
 
WAIT!!!!
I saw something! (SSSAZZAAANNN!!!) I saw the light! I'm cured! I touched the screen....eeeerr the fold out page of FAOW21! Nohara has a color profile of the 5th Sentai painted overall green. It's like the planes in pages 46,47,48,52,53,81. They are all Green!!! Just like you said so. I'm finaly able to reach the highest levels of happiness thanks to you guys!
But why does the underside color look THAT dark? Check photo in pages 46,47. The undersides don't look dark at all. The color looks to be applied in a very uniform way, from the nose to the tail wheel in p.48, top.
Well, I don't know. I'll follow your advices and build a Manchurian Toryu (?!?!?!?)...someday.

Re the argument that it's illogical to paint the underside of a dark plane black, in Asahi Journal 4,1 p. 20 under an illustration by the above Don Marsh, Tom Hall says of a dark colored illustrated 53'd Sentai Ki-45 Tei, "Few of the 53rd's planes were seen in [this] overall brown or olive scheme. Although called a night camouflage, it was not satisfactory for the underside of this plane, which was clearly darker and probably black." and is illustrated as such. His source is Koku Fan 80, pp 111, 113, 126-8, which I'm afraid I don't have, but, if accurate would suggest that in at least one sentai dark a/c received black bottoms. (IMHO the bottom of the a/c on p.49, FAOW, is indeed black, there may even be a demarcation line on the bottom of the port cowling.)
Incidentally, the Nick illustrated in Asahi Journal also has a white, or cream fuselage bandage. What were they thinking?

I'm trying to fill in some gaps on the technical specs of the Type 94 tank gun carried on the Otsu.
 
I have that it fires a .460 kg shell at 640 m/s, but I was wondering if anyone knows how much the complete round weighed and how many rounds were carried. I imagine that since it was hand loaded, the crew could take as many or as few as they wanted, but maybe there was a standard.

I have 644g at 580 m/s for that weapon, from a 37x133R case. By comparison, the Ho-203 used a 37x112R cartridge (475g at 570 m/s) and the Ho-204 used the 37x144 (475g at 710 m/s).

Thanks for the responses, everyone.
 
Was there any difference in weight between the AP and HE rounds? I found this pic on a tank site, and they're pretty different size-wise.

The Japanese tended to "mix and match" the different 37mm case types with a standard range of projectiles.
 
The standard HE projectile for the Type 94 tank gun weighed 644g (mv 580 m/s), the normal AP (which had a small HE content) weighed 700g (573 m/s). The AP projectile may be smaller than the HE, but steel weighs much more than chemicals!

Don't know the answer to your question but type 2 fighters captured at Noemfoor Island in 1944 carried the Ho 203. Most were fitted with an 18 round magazine. One had a 25 round magazine. Allied intel considered the Ho 203 but little improved over the earlier tank cannon.
 
I would infer that a hand fed cannon would be unlikely to be armed with more rounds than an automatic cannon given the difficulties involved in loading. My guess 10-20 rounds.To be very clear, I have no data that provides direct evidence to support my guess.
 
Perhaps someone else on the board can help us out.

That's interesting Rick; the sources I have say that the Ho-203 had a continuous-loop "squirrel cage" magazine looking very similar to the one used by the US 37mm M4 in the P-39, but it held only 15 rounds. I haven't heard that it was available in different sizes.
