I recently aquired a 1917 DWM Luger with all matching numbers. The magazine is aftermarket junk. I know nothing about Lugers and would appreciate some help with the history on this one. (WWI,WWII use?) I have visited several websites for info but ran into brain overload. Hopefully there are some members here who can tell me something from their personal knowledge. I will be showing it to several thousand folks this year and like to sound like I have a clue about what I am displaying when they ask questions.
