I have a 7 mm mauser, dont know the origin. My grandfather was an avid gun collector and this rifle was handed down to me. It has "1895 LOWEN BERLIN" stamped on the side. Just above or on the side of the bolt near the safety appears to be some sort siscle stamp (excuse my spelling, it resembles the old soviet symbol). It has iron sights with an elevation slide. It has a huinter stock on it my father put on because the original stock was lost but would like to find a replacement. You guys have any clues?
