Same on both sides. I figured pics of one side would be enough so I’m not bombarding the thread with images. 😁
I’ll be in contact with the owners and see if I can’t get a closer and deeper look. They also have a B-25, a couple P-51s, a couple P-40s, an FM2 Wildcat, a Hellcat, and an A6M-2...
Hopefully these help. I just took them on 18 June 2022 of the Fagen Fighters F-5G-6-LO (P-38L) (USAAF 42-7231 / MSN 422-8235) painted as P-38J "Scat III" of Robin Olds.

I forgot to get a shot of Sta 289 for you...
If you go to NASA Technical Reports Server (NTRS) and start a search for something as simple as "cowling" you'll get all sorts of interesting hits.
Some examples:
Preliminary Investigation Directed Toward Improvement of the NACA Cowling (1942)
Cooling Characteristics of a Pratt and Whitney...
Yes, which is why I ruled it out.
I think what we’ve discovered in this discussion was that there really wasn’t a single engined radial solution to the Circular Proposals in question. Unless we get really goofy and go for something along the lines of the XP-52/59.
I may try a conventional twin...
Something less than a P-47. But more than the P-43. As I was drawing it I certainly saw the resemblance—but something else was creeping in there too as I was trying to find clever packaging solutions: this almost seems as American FW-190.
Here's my attempt. Although the trouble is that CP.608 specifically called for a Twin-Engine interceptor so this would have to be in response to 609 (which led to the P-39). The other roadblock I'm running into is getting the proper armament fitted. I just can't find a way to fit 20mms much...
Cool design, Tomo! A few little things I noticed are the use of the actual P-38 canopy shape but changed to a sliding (or is it side-hinged?) three-piece affair. Also, it appears you used Republic wings--I wonder if adapting the 23016-to-4412 trapezoidal wings as used on the real P-38 would be...
And in looking at that report again I realized I mis-spoke in my previous post. Tomo was indeed correct that the three options were .1c extension, .2c extension, and the 66-115 "glove" at 1.2c rather than a .2c extension and 66-115 at 1.1c and 1.2c as I mistakenly said.
The final conclusion is...
That is one, but not the original report. The original report and investigation was "Guryansky, Eugene R., and Preston, G. Merritt: Full-Scale Wind Tunnel Investigation of Buffeting and Diving Tendencies of the YP-38 Airplane. NACA MR, March 1942." It appears the old link I had is no longer...
Yeah, been busy with offline life...house projects, moving, etc. I saw the link to this discussion on that other site we're on and figured I'd pipe in. About to join the discussion over there as well.
As Tomo knows, I have done some pretty deep research into this topic. There is a lot to unpack in this discussion but the basic idea, of using a thinner wing on the P-38, poses a few problems, not least of which is the afore mentioned reduction in fuel capacity. There is also potential...
Thanks, I think I will enjoy being here. It is right up my alley. ;)
Yup, Rau's letter is a bit of the "gold standard" for P-38 researchers trying to understand the contemporary experiences at that time, c. March 1944.
The most interesting bit from that letter was the mention of the "Unit...
The pilot's manual simply says "Late airplanes" or "later J Models." As best I can find, this corresponds with the J-15 (which added the second generator on the RH engine as well as other improvements) beginning with #42-103979 and would have reached combat operations in Early '44 (January or...
