A fired .50 BMG case stamped “97 15”, Brass, primer annulus polished off. Can anyone tell me more?
The headstamp format looks South African to me, with the top entry being the date and the bottom entry being the model and mark, so to speak.
South Africa did come to mind actually, as they are the only ones that use Eastern-Bloc style headstamps the opposite way up. Would “15” be Mark 1, .5"?
Eastern-Block used Factory code and year. The South-Africans as said above year and model. 1st figure gives the projectile type and the second it’s modification.
