1:72 scale diecast aircraft by Hobby Master. Aircobra AH601 (P-39) 601 "County of London" Sqn., Duxford, Oct 1941.

From the manufacturer:

The P-39Q has the distinction of being the most produced series with 4,905 built. The Q also was the last version of the Airacobra to be made by the Bell Aircraft company. The main difference between the Q version and earlier versions was the replacement of the 4 wing-mounted 0.30 ¡V inch machine guns with a single 0.50 ¡Vinch machine gun mounted inside a pod attached to the bottom of each wing. The P-39Q-1-BE also regained the additional 231 pounds of armor of the P-31N-1.

The only RAF unit to use the P-39 was the 601 Squadron. Based on the performance of the test model the RAF ordered 675 of these aircraft armed with 0.50-inch machine guns in the fuselage and four 0.30-inch machine guns in the wings, the 37 mm gun was replaced by a 20 mm Hispano Suiza. What the RAF received were aircraft without the turbo-superchargers severely reducing its effectiveness and after only one operational use by the 601 these aircraft were deemed unfit with further orders cancelled and the aircraft removed from service."
