Hey everyone,
I went ahead and picked up the P08 yesterday. I talked him down to $655, which I'm content with (the magazine turns out to be an original FXO 37 proof magazine as mrerick mentioned previously, in pretty good shape with most of the original finish, a plastic base and a strong spring, although there is some wear and a chipped plastic lip on the left side of the magazine). The owner really stuck to the story of this Luger being a vet-bring back, so he was pretty firm on the cost, but all things considered I feel it was a very fair deal.
After field stripping and a closer, inspection, the finish isn't
as bad as I originally had thought, and it turns out the leather USGI holster is in worse shape than the Luger. The inside looks great and is very clean, and on a related note; all the numbers appear to match, from the firing pin to the toggle train to the barrel, aside from the post-war grips. In addition, I couldn't find any peened markings, build stamps or import marks on the pistol, nor any attempts to hide any. I picked up some Winchester white-box 9mm rounds earlier today, hoping to get to the range soon to see how she shoots. I'll take some pictures when I break her down for cleaning and post em on here so everyone interested can get a better look.
Thanks again for everyone's help, I've learned a great deal and hope to learn more, as I've been certainly bitten by the Luger-bug...
