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).

On post #82 you can see Apophenia's superb Model 3 render.

Sorry Please find attached Model 2 drawings and performances
Span 30 ft
lenght 25 ft-10 in.
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.

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

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

From old site,
since the late 1930s, Bell has been conducting numerous studies on various types of combat aircraft for the US Army Air Corps. These included fighter aircraft designs, although most of the small company's efforts in this area were, of course, consumed by work on the contract to build prototypes of the XP-39 "Airacobra" fighter .
One such design study, developed in mid-1939 by engineer J. Trotter, was a small, light fighter aircraft designated the Model 11. It was a sleek, low-wing monoplane with compact dimensions, reminiscent of the racer planes popular at the time rather than combat aircraft. The trapezoidal wings with rounded tips were to be equipped with automatic leading-edge slats. The aircraft was to have a covered cockpit and retractable tricycle landing gear with a tailwheel, with the main wheels retracting into the wingtips and the tailwheel retracting into a recess in the rear fuselage. It was to be powered by the then-fashionable Allison V-1710 inline 12-cylinder engine. Unlike the P-39, however, the Model 11 had a classic design layout with the engine located at the front of the fuselage. The armament of this light fighter was to consist of two machine guns mounted in the front of the fuselage above the engine.
The Model 11 never progressed beyond the preliminary design stage and work on it was discontinued. Little information about it survives beyond factory design drawing number 11M001. It is likely that the Model 11 was just one of several proposals developed by Bell in preparation for the R-40C competition announced by the USAAC in 1939.
Tactical and technical data (designed):
Design: single-engine, single-seat, low-wing, cantilever monoplane with an enclosed cockpit and a retractable tricycle landing gear with a tailwheel. Classic, cantilever tailplane. Metal construction.
Dimensions
span 9.14 m
length 8.79 m
supporting surface 15.47 m2
Masses
curb weight 1974 kg
take-off weight 2532 kg
Performance
no data
Propulsion: One 12-cylinder, liquid-cooled, V-shaped, in-line Allison V-1710-37 engine, rated at 813 kW (1,090 hp, 1,105 KM) at an altitude of 4,023 m, driving a 3-blade, 3.2 m diameter, metal pitch propeller
Armament: two fixed 7.62 mm (?) Browning machine guns in the front part of the fuselage above the engine
Crew: 1 person
Manufacturer: Bell Aircraft Corporation, Buffalo, New York, USA
Production: design only
