In 1940, the Pitcairn Autogiro Company became the Pitcairn-Larsen Autogiro Company. Their last design was the PA-44, which was ordered by the U.S. Army Air Corps as the XO-61 early in 1941, but by that time the A.G.A. Aviation Corporation had taken over Pitcairn's activities.

The A.G.A. Aviation Corporation didn't last for very long, and soon it became the G & A Aircraft Inc. division of the Firestone Tire and Rubber Company in 1943.

The first design under that name, which owed a little to the design of the PA-44 autogyro, was the GA-45B, a helicopter that was ordered as the XR-9A, then cancelled. The GA-45C, however, was evaluated as the XR-9B. A civilian version, the GA-45D, was also built in prototype form, but failed to attract customers.
