At the passing of my father earlier in the year, I received a rather pitted 1918 DWM Luger with one grip missing, matching #s and no mags nor holster. serial# 7859 with some cursive letter beneath it. It has small eagle on both sides of top along with I don't know what followed by two things with crowns on top and then the eagle on the right side. The barrell has 8,82 on the underside. Does have lug on back lower portion of grip and gold color to trigger but nothing else. I think this is a shooter or restorer due to the pitting and almost no evidence of blueing. What do you guys think?
