Stinson was a division of Vultee so this may be called the Vultee L-5 Sentinel in some sources.
The Stinson L-5 Sentinel was developed from the three seat civilian Stinson 105 Voyager. The L-5 was ready for production in 1942.
An order for 1,731 was placed by the military.
The L-5 Sentinel could be modified so that it could be an ambulance by carrying one stretcher.
The L-5 was still being used in the Korean War.
