The OY-1 was the USN designation for the Stinson L-5 aircraft that were transferred from the USAAF to USN. The Letter O stood for "observation" and the letter Y was the manufacturer code for "Consolidated Vultee". In the USAAF designation, L stood for "liaison". Stinson was aquired by Vultee which became part of Consolidated by the time of the transfer. The navy distributed the OY-1s to the five USMC observation squadrons (VMO).
