A buddy of mine swapped a boat motor for a rifle many years ago. He didn’t know anything about the rifle and just recently pulled it out of the safe and asked me to tell him what he had. The truth is, historical firearms just aren’t my thing, so I’m not much help, but I told him I knew exactly where to get some answers. I’m attaching the only photos he sent me, but my initial thought is that he has a sporterized Mauser of some sort. Any idea of value would also help. If it’s worth it, I may buy it from him. Thanks in advance for what I know will be some solid answers.
