I have 8 qualification bars that are attached to an Army Expert marksmanship badge that I can't identify. Does anyone know when these bars were authorized and / or de-authorized:
1) EX. RIFLE
2) S S PISTOL
3) EX. BAYONET
4) PISTOL - A
5) PISTOL - B
6) PISTOL - C
7) CORIDA
8) S.S. B.A.R.

None of these seem to be currently authorized. The bars are all the WWII style nickel finish. Two of them are marked GEMSCO. The rest are unmarked. The CORIDA is particularly baffling. Is it a weapon?

Here are three of the qualification bars with the CORIDA bar at the top.
