Hello, do any of you have some ideas on this gun's story? I received it when my German born step-father died; unfortunately his death was quite sudden and I didn't get a chance to learn about the gun's significance. I hope that it is older than the stock indicates... probably was converted for sport a while back? Some of the identifying stamps have worn off a little, but I think the stamp on top of the muzzle reads BNZ, while the stamp on the bottom near the trigger is BYL or BYF. To the left of the BNZ the serial number of 6371 is stamped, and the same number appears on the bolt lever and the safety switch. Also not sure what the scripted letter is, maybe a 'P'? The gun shoots 170 grain 8mm ammo just fine. Any thoughts or advice? Thanks!
