I just obtained a Waffenfabrik Oberndorf aN 7x57 Sporter. I wondered about something? The receiver ring is marked the same, as the early run of SWEDISH MAUSERS made in Germany were. It is all matching with SN 4582. The cocking piece, safety, and bolt handle and shroud look nothing like a Swede. The triggerguard assembly is set up for a set trigger. Commercial...Custom...European[my guess]...American? It has German proofmarks but just what is it? What say you?

RIFLE ARRIVED ADDENDUM: Beautiful rifle, the bore understandably is dark but shined up and is not pitted. I've used Copper cleaner and a TINY bit or Flitz Liquid Polish. The patches are coming out the color of a No. 2 pencil mark. ANY SUGESTIONS FOR A 110 YEAR OLD BARREL for what appears to be heavy lead and powder foulings ?
