I am hoping to get some information about my 1911 DWM Luger just purchased. Serial number is 1751e, and all numbers match (including grips), but no matching magazine. I don't think it has ever been refinished, and the straw parts are a little tarnished. Bore is a little dark, but strong rifling, and it shoots great. No hold open, unfinished inside, and marked like I think 1911 DWM Lugers are supposed to be (i.e., not visible military style numbering, but hidden like a commercial Luger). No unit marks, but at some point, someone engraved the name "N. F. Doerr" on the side of the frame. Anyone have any thoughts of who Mr. Doerr could be? I have tried to find German and American soldiers with that name, but nothing definitive. Probably too much to ask to find Mr. Doerr, but wouldn't that be great? Thanks in advance for any help you may give.
