These personal checks featuring the Cunningham-Hall Model PT-6F is a great design for airplane enthusiasts. Made by the Cunningham-Hall Aircraft Corporation of Rochester, New York, the predecessor version (the PT-6) first flew on April 3, 1929. It was an all-metal construction with a fixed landing gear and a tail skid. The cockpit held a pilot and either a copilot or passenger, with a separate cabin for four passengers. The company modified that into the PT-6F, with its maiden flight in 1937. It was modified to provide a larger cargo compartment and freight door added to the fuselage and a loading hatch fitted in the roof. It was powered by a Wright R-975E-1 radial engine.
