I realize this is not a "doubles" topic, but need some information. A friend of mine has a German made rifle for sale. Don't know anything about it. It is a single shot bolt action. Has a lot of engraving on the receiver and on the wood. One one side of the barrel it says Bohler Stalh with HL under that. The other side reads A Strover Nordhausen. Does anyone have any idea of value of this gun. I don't have a clue what to offer. Appreciate your help. George
