Can anyone help me out with any info on this pistol? From the little bit I could find, I think it's a 1937 S42 German Mauser Pistol, a P08 maybe? Also it looks like something was carved in the grip on the right side, any ideas what that is? Looks like r B maybe. Any ideas of a value? I may end up selling it, if I can figure out what a reasonable price would be. I don't know if the holster is original or not, but it seems to be pretty old and wore out. The numbers on the bottom of the magazine do not match, I don't know if that makes a difference or not. The other mag is a newer Mec Gar magazine. I tried to get pictures of all the markings the best I could.
