Stinson Model 108
First developed as the Stinson Model 105 in 1939 it was a high-wing three-seat braced monoplane powered by either a 75 hp Continental A-75 or a 80 hp Continental A-80-6. This was developed into the Model 10 powered by a Continental A-80 piston engine. The Model 10 introduced a wider cabin as well as improved standards of interior and finish. The Model 10 was followed by the Model 10A powered by a Franklin 4AC-99 engine and the Model 10B with a Lycoming GO-145. Six Model 10As were evaluated by the United States Army as the YO-54, the successful testing led to an order for a slightly larger and heavier O-62, later designated the L-5 Sentinel.
A number of Model 105s and Model 10As were impressed into Army service as the AT-19 (later L-9).
