I am looking for help with older heym rifle. The action is mauser 25.06, with plain wooden stock. the Barrel is blue with the bolt being a chrome looking finish, a little slop in the bolt when open like a lot of Mausers. It is stamped on right made in Germany, and and on left side it say St. Hubert co. and Waseca, MN. On the right side on the barrel it is stamped 25.06. I think the gun was acquired in the 1960s or early 70s by my father in law, but it might have been a little earlier. Any help with this would greatly help my curious mind about the history of this gun. It shoots beautifully to this day with a Zeiss scope on it. Thanks for the help Dale
