Greetings from Tennessee. I inherited a sporterized Mauser from my father-in-law. It has a modified military stock and a large rig Mauser receiver. It is mated to a 30-06 barrel from a J. C. Higgins Model 50 rifle. The S/ f the recever is 6195, has a waffenstamp, also eagle over 280. I want to date the action but no date stamp on top of the large ring. How can I date this action? Any help would be greatly appreciated.
