Justo,

would you please post Model 2 picture? I'd love to see it.

Model 3 and 4 were both fighter projects from 1937.Both were preliminary proposals submitted by Bell to Army Air Corps specification X-609 issued on March 1937 for a single- seat, single-engine (V-1710 with turbo-supercharger) high altitude interceptor.
It would have been a complementary type to the winner of X-608 (Lockheed P-38) for 1940-45 USAAC fighter force, according to US aislacionist policy from that years.

Armament for Model 3 consisted of a single 25 mm cannon and 2 0.50in machine guns (option for 2 more 0.50in MG) in forward fuselage. The engine was placed between the nose and the cockpit. It progressed to full-scale mock-up only because of poor visibility. It latter influencied the design of Model 32/XP-77

Tech Data: Span: 10,67 m, Lenght: 9,04 m, height: 3,61 m, Wing Area: 27,78 m2, Loaded weight: 2,446 Kg.

Model 4 reversed Model 3 cockpit/engine position. It was selected as winning design and further develoment resulted into Model 11 (XP-39) and Model 12 (YP-39).

The Bell model 2 is in fact the model 11.
(maybe there's confusion with Roman figure II)

The design was smaller than the P-39.
It had a span of just 30ft ,four ft less than the Airacobra.
Fuselage lenght 28fr 10in.
Selected powerplant Allison V-1710-37 engine.

The model 11 was apparently in response to an Air Corps competition in 1939.
Bell's priiminary design wa completed during the middle of 1939
and may possibly have been an internal designs study in preparation
for the R40-C competition.

Mmm...that Bell Model 11 looks more in the class of XP-47 than later Bell's Model 13 entry at R40-C.

Maybe it had the looks but infact it
was a small-see dimensions- conventional pursuit design...
(project engineer was J.Trotter)

Woods was the project engineer for the models 13 ,13A and 13B.
proposals to R40-C

Source is the Bell Aircraft modelnumbers list.

I agree with you. Please see that I talk about XP-47 (and also the XP-46) category not the XP-47B :)

You're right of course Pome..
XP-47 and XP-47A were much smaller pursuit designs
like the model 11 in the the true late 30's fashion.

The info I put here was found in the indispensible " Cobra" - Schiffer
