Top: Boeing XB-38. A B-17 fitted with 12 cylinder Allison V-1710s. 1 built. Flew in May/June of ‘43.
Bottom: Boeing XB-39. A B-29 fitted with experimental 24 cylinder Allison V-3420s (two V-1710s yoked together). 1 built. Flew December of ‘44. Neither went into production because in each case, the modest increase in performance didn’t warrant interrupting production scheduling to make the necessary changes to the assembly lines.

Never heard of the 3420 and stumbled on this rig. I worked there 20 years and never knew GM (Fisher Body no less) built a fighter, let alone with a 3420 in it. A little ungainly looking (front/top heavy) to me, but apparently as good as any prop fighter of the era.

Didnt go anywhere: Fisher P-75 Eagle - Wikipedia

Allison V-3420 - 1930's design, slide rules and pencils. Always amazed at what those folks could do. supercharged and turbocharged.

This b-24 crew completed a 35 combat mission tour: 14 October 1944 - 20 March 1945. bottom row in the middle is friend of mine grandfather. he was mostly a waist gunner but sometimes he was a tail gunner.

What is that? I don’t recognize it.
my educated guess? B-17.

clues? skin, nose & belly guns, four props, wheels going into bottom side of inboard engines, big-a** horizontal stabilizer, wing shape (though I cant see the tips), and a lifelong model buildier of WWII planes :).

Fastest Prop planes ever. Some on the list I would never have guessed and never heard of.

I never debate you brother, but im sticking with my guess Peter. :)

Dunno the B50 but it looks too big (length, wingspan, WASP majors are BIG too)

By all means , debate. I know nothing of it except what I found on the image search, which is not always 100%.

I thought that too. Must be an early model.
I too built a lot of plastic models. Now I am working 1:1 scale. 8^)
