I have aquirred a BYF code 42 mauser in excellent condition and it has a Black hard shell holster that is waffen stamped WaA101 with the straight wing eagle over the world an a swa stika inside the world or globe. It is marked PO8 and the year 1941 and here's what I'd like a little light on. The holster has glg or gig near the date 1941; Is this the maker mark or city code, if so who is it and where was it made? This setup is a vet bring back and I cherish it very mush. All info on it woud be appreciated or tell me where I can go to get info on it would be great. Thanks
