37mm shell case

[dano1917]

My wife went to the antique mall yesterday and saw this shell casing and picked it up for me! It measures 50mm across the base (I assume it had a bottle neck on it that someone cut it down). On the base it reads 37 MM
BB - / - 94 - 1944 and in real small lettering around primer it says LS 6 - 208 M 3 BB 2. Can anyone tell me anything about this casing. Obviously it is WW2. Is it a U.S. casing? Any help appreciated. Dano

hello

It's a 37x222 US M17 shell for the 37mm M1A1 and AN-M9 gun. Unfortunatly it's cut down. You don't see them often, mostly you see the 37x223R M16 shell.
