All I can tell you is that the 765 is probably7.65 cal. or 32acp. The rest is a mystery to me, good luck. Don

Some additional info for you on that pp... the ac means it's made by walther during ww2, zella mehlis was destroyed at the end of ww2. The post war pp's were made in ulm germany. So, it appears you have a pp made during ww2, not a postwar trade in. Just a guess the other markings could be east german. hope this helped you a little. don

Here Iam again with more info. The 1001 number says that it is a east german copy not a real walther pp. sorry don
