A good friend of mine recently acquired a 1937 S/42 Luger handgun from his late Grandfather. He is not interested in guns and doesn't want it but he has know idea what it's worth. I have exhausted my Google-fu and I am still not sure. I know that it is not a complete #'s matching gun. The serial number is 6645 i. All parts are numbered 45 except the trigger, firing pin and one other piece that are all marked 03. Also the left side grip is numbered 50. I have been able to find what I think are some of the proof marks online, but not all of them. I would love to post pictures on here or a Luger forum of the marks, however I don't have a camera other than my phone. I am planning on taking it with me to the 1500 on Saturday. Does anyone know of anyone there that would know about them? Or is anyone on here going to be there Saturday that would be willing to take a look at it?
