3 1/8" U.S.A.F. F-100F "Super Sabre" Radio Magnetic Compass Indicator. Manufactured by Pioneer. P/N 5916-46A-1-B.
The F-100 was the world's first production airplane capable of flying faster than the speed of sound in level flight. It was used extensively as a fighter-bomber in ground-support missions during the Vietnam war.
Very clean item. It shows well and it would make an excellent desk top or bookcase show item for the office or home.
