Gator ... I'm not really a "Mauser man" as much a Military Rifle Obsessed Individual. The real "Mauser man" is John Walters. I think he knows more about Mausers than anyone alive and has done a couple of good books on them. For me, the dead giveaway were the receiver markings in addition to the "overall" on the rifle itself ... receiver, stock, etc.
Nice Kar98k, by the way. I have one produced in '37 and another in '44. Both are fun shooters, super easy to reload for and if any of you guys don't already have one in your rack ... you need to get one!
