Built as a L-5B for the USAAF in 1943, s/n 42-99699, transferred as an OY-1 to the USMC with BuNo. 02766.

Remarks by Howard Rundberg: "We installed a small UHF (Ultra-High Frequency) radio transceiver in a Marine Corps OY-1 Sentinal observation version of the Stinson Voyager and performed flight tests to evaluate two proposed antenna locations. Because the back seat area was small, I had to put my seat-pack parachute in first, then get in and buckle up. As soon as we got out of the pattern the Navy pilot said: "You know what you want to do, so go ahead". I drove it on up north at 5,000 ft (1,524 m) while periodically switching antennas and checking signal strength back with the base. When we returned and landed I couldn't get out. I had buckled one of the parachute straps around the aircraft seat leg. The Navy pilot laughed and asked if I had been an Air Force pilot."
