Luger with mismatched extractor
Hello,
Bear with me as I know this is a very vague question. I plan on looking at a Luger tomorrow, dated 1941, accompanied by a holster. My question is, if all serial numbers match except the extractor, what kind of a value detractor is that? In reference to collector value, that is. Assuming the pistol is about 95% blue, nothing else special about it like a rare maker etc. The asking price is $1200. I apologize for the vague nature of this thread, especially lacking photos for an evaluation, but this only came up today as a possible purchase and I have never dealt with Lugers before. I appreciate any information that you can give me!
Thanks.
P.S. As I stated I have little knowledge of Lugers, the seller likely has less. Is it a bad idea to purchase this if I have not had it stripped to check the various small serial numbered parts not visible when the pistol is assembled? I certainly would not be skilled enough to do that.
