My brother inlaw dropped off a rifle that has been in his family over 50yrs, never fired by anyone.He asked me to clean it & figure out what it was & the caliber. I was amazed when I opened the case & saw this mauser, Now I know nothing about mausers All I could find online was this was probably made 1944, But I cant be sure if its an 8mm nothing stamped regarding caliber. Every number is matching even on inside of the stock Natzi symbols stamped in a bunch of spots. Any info would be great Im trying to attach pics. Thanks
