America US Air Corps Collar Badge Disc - Two Piece
A 2 piece, gilt brass, with nut, collar badge to the American US Air Corps.
Unsure of date, so either 1937 to 1943 or post 1970.
Some wear to gilt finish, especially to front of disc, which is now a dark tone.
To back is the nut, thread post and two spikes, all in good order.
No maker mark.
