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 SLS is a piece of work. 15% more thrust than the Saturn V. Apparently a real bad-a** - most powerful we've ever built at nearly 9M lbs thrust. Must be the "shoes"

What is that? I don’t recognize it.

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 .

Boeing B-50 Superfortress

The Boeing B-50 Superfortress is an American strategic bomber. A post–World War II revision of the Boeing B-29 Superfortress, it was fitted with more powerful Pratt & Whitney R-4360 radial engines, stronger structure, a taller tail fin, and other improvements. Wikipedia
Top speed: 636 km/h
Range: 7,886 km
Wingspan: 43 m
Retired: 1965
Length: 30 m
Engine type: Pratt & Whitney R-4360 Wasp Major

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%.

fastest prop plans ever. apparently the hot rod props of their day. I was surprised more by what is not there. rank below slowest to fastest. I argue the two fastest planes aren't "real" (never commercialized, never fought in war, etc)

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^)

I defer to your wisdom...

I think it’s a B-17B
