The Curtiss OC-2 was originally manufactured as the Curtiss F8C-3 Falcon. But when they were delivered to the U.S. Marine Corps, they were redesignated as OC-2. This image of A-7968 showing the U S Marines badge is probably taken at Naval Air Station in San Diego between 1929-1931. Scanned from an original reproduced photograph from my collection, date, and photographer unknown.
