I saw a strange K98 at a gun show yesterday. It was marked Standard Model on the side rail but I could see a very faint S/237 and 1939 on the receiver, looked blued over, with a Mauser logo stamped between. The MO logo showed signs of rusting. No WaA on the receiver. Dealer said it was a Mauser Banner and was very proud of it. No other parts matched the receiver. I’m thinking a phantasy fabrication.
