birfWaffenfabrik Walther Zella-Mehlis (Thur.) Model 8 Is the full name, I dont know if that means anything special. Basically, my grandfather liberated it from a Tiger tank commander when they took it out on foot(And apparently took a round from it, too.) It was lost since about the 70's, and I found it at my grand mothers when helping her move some files around the house. My father and I have cleaned it and put about five rounds though it, but the ejector/extractor only seems to work twice before it fails and the casing stove-pipes at best. This is the exact same thing that happens simply cycling rounds by hand as well. I'd like to get it back to its original condition, my father really doesnt agree with that, but honestly, this is a historical piece and it deserves to look good and be able to shoot.
