Hi!

So as the story goes, my Great Grandfather bought an old pre-war Mauser off of a returned soldier in the late 40s-early 50s. I finally got a chance to look at it just two weeks ago. Its a beautiful gun, but I'm absolutely baffled trying to identify it. As far as I suspect, its some form of sporterized Mauser 98. I know it was rechambered from 7x64 Brenneke to 7mm Remington Magnum, and that the scope was added in the 1950s. I have heard that an Ed Striviak? worked on this gun, but I have not been able to locate any information on him.

I saw some similar looking guns on this forum, such as this: http://forums.nitroexpress.com/showflat.php?Cat=0&Number=208805&an=0&page=0#Post208805

The thing is, I can't really find any identifiable markings. All except 3 proof marks are hidden between the barrel, receiver, and stock. I have found the Crown B Crown U proof marks, as well as the Eagle N and Eagle J marks which would maybe date it to late 1930s/early 1940s. There is "GFZ" in an oval, but I cannot find anything that matches that. There is also the number "39" but I don't know if that is a year or not. There are the initials "G. M." near the receiver, and it looks like it matches the scrollwork. There is also the name K. Barthelmes, but that also is an enigma. I have found that the Barthelmes family were prominent gunsmiths, but I haven't located any "K" member. I don't know if they are serial numbers, but I have found both 3270 and 8270, on the barrel and receiver receptively. Oddly, in both instances the 70 was stamped separately but next to the first two numbers. The bolt also has a 70 on it. There is a 1041 underneath the Eagle J proof mark but I have no clue as to what that means.

The scope mount lists Paul Jaeger, Jenkintown PA. Unfortunately I don't think the scrollwork was done by him however - I understand he wrote his name on the barrel of all his guns. The scope itself was manufactured in the 1950s, and still works nicely.

I guess what I'm looking for is any way to find out more about the history of this particular gun. I'm completely baffled at the markings. I have no intention of selling it, but I also have no real idea of its value. Its in great condition at the moment, and I'm definitely going to cherish it.
