Bell YFM-1A Airacuda Handbook of Operations and Flight Instructions

This is an original 24-page flight manual for the pre-war, experimental multi-place fighter the YFM-1A Airacuda designed by Bell Aircraft, dated December 1940.  The highly unusual design, with its twin pusher engines and forward gunners stationed on the wings in the engine nacelles each operating Colt 37mm automatic cannons, did not see combat despite 13 of the YFM being built for test. More about this aircraft can be read at its Wikipedia entry.  A highly unusual aircraft and a rare manual.
