This is a hard one to identify. I have always called it the Humphreys MG-2 because he has the emblem "Humphreys Special" on the tail and it was registered to the Humphreys Aircraft Corporation of LaCrescenta, CA, as the "Falcon MG2", However it was built as the Melberg-Greenemeyer MG-2, thus the "MG". See the story in SPORT FLYING for Feb 1970. This photo was taken at the San Francisco Bay Airdrome in Alameda in 1939 when it was operating as part of the "Tex Rankins Hollywood Aces" airshow team. Put Humphreys also flew a Ryan STA with the front cockpit covered as part of the show.
