If you are talking about the 74th fighter squadron, USAAF. They were established in the Far East (Flying Tigers), flying P-40 Warhawks, and later P-51 Mustangs. If you go to ashra.af.mil you can get an accurate patch. By the way, they are still an active operational unit. They are currently flying A-10C Warthogs and F-16C Fighting Falcons. They are also based at Moody Air Force Base, Georgia.
I hope that helps
