I love talking about guns as well, especially Mauser rifles
Looking at my M98 bolt next to the ones in these pictures, the only notable difference I can tell is the bolt handle is flat on the bottom of his, whereas mine is completely round.
Looking at the left side of his receiver, I can't quite see what it's stamped with, but it doesn't say 98 or 95 anywhere on it :-\ The Germans were so much more clear about that lol. Mine is stamped Mod. 98 right on the receiver. As if the obviously peened swasticas and eagles weren't enough to give it away
