Hello, I bought my very first Kar98k last Sunday ! I am more than happy with it, it's a 1938 S/147. All parts match, including barrel channel, stock, bolt, action, etc...BUT it's a KNM (Norwegian Navy) capture rifle. I read somewhere that Norwegian Army and Air Force Mausers were re-chambered in 7,62 m/m after the war, whereas Navy Mausers retained their German calibre. This said, how can I be sure of that ? There's no "7,62 m/m" stamp on the barrel. And what are those stamps on the barrel, once the barrel channel removed ? What do you think about my rifle ? Your advices would be very welcome ! Thank you in advance.
