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. It was registered to the Humphreys Aircraft Corporation of LaCrescenta, CA, as the Falcon MG-2, 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 when it was operating as part of the "Tex Rankin's Hollywood Aces" airshow team.
