I believe that to be a M7A3 grenade launcher. I would need more detailed photos. See above link.


Das Boot Post war German cases:
Rifle Grenades Small Arms Defense Journal

Thank you 72 usmc, the case is German and the launcher is usgi. It makes sense since the Germans used our m7a3s post world war II, that they would use their grenade launcher cases with our m7A3s as well. He said he'd had it a long time and always thought that case went specifically to that launcher. I told him that I had never seen or heard of a grenade launcher case for usgi launchers, but I would try to find out exactly what he had. Thanks again
