The Luger on your "site" is a nice "sight."
Did Shostle also engrave the Luger? The stag grips look nice on it. You should give the Luger data; manufacturer and date. And tell if the plating is nickel, chrome, or silver.
If the engraving didn't remove the manufacturer's name or code or date, I can tell you who the maker was by the code. Of course, if it says DWM, Erfurt, or Mauser, you already know that.
Many here can do that. We aren't all limited by tunnel vision on guns and know only Smiths. It bugs me when someone says he just knows S&W's and some claim to know only about, say, N-framed guns! I think we should have wider horizons.
I'll help if I can, but there are others who know Lugers better than I do. I hope they see this topic. That's an impressive gun.
