I falchi di Rangoon

Being born in 1939 I grew up watching all the John Wayne movies and remember quite well the impact this film had on me and eventually my chosen profession as a pilot. The question that always comes to mind whenever I see the film is; Who built the P-40 Warhawk replicas used in the movie? I assume Curtis-Wright had a hand in it as they are mentioned in the credits. The replicas were done fairly accurately and obviously had an engine and propeller with enough power to taxi. This also means that they had a steerable tailwheel and main landing gear brakes for stopping etc. Noticeable though is that while taxiing you do not see flight control surface movement especially in the rudder which would move with the tailwheel. No aileron movement is observed either, which you would see during taxi over rough ground and the pilot's hand holding the control stick naturally would transmit some vibration to the ailerons. The most obvious difference from the true P-40 is in the area of the canopy and windshield construction, kind of close but not convincing when the actual footage of aircraft taking off shows the true configuration and size of the aircraft. The film is not "TOP GUN" but is always a nice nostalgic event for this old retired pilot.
