lets see some pics, esp some detail of the 'nazi' marking. I don't think that Walther made PPK/S during the war, they made them for export to the US, well after WW2. Does it say PPK/S on the frame? Also, you mentioned that it was in 9mm. It actually is 9x17mm Browning, aka .380 ACP or 9mm Kurz(which I think is what it says on the frame). If you intend to shoot it, don't try to buy/ load and shoot 9x19mm Luger. I wish I could inherit a PPK/S. I am buying one here in early May. You might try asking with pics over on Waltherforums.com, there is a lot of expertise over there.
