Walther PPK: Identifying Your Vintage Pistol - Markings & Information

Question
I was curious if you could give me some insight to an older Walther PPK I own.  This piston was given to me by a friend and the information is as follows

Answer
Jerry,

Was there some additional info you were going to send me?  Your email said there was some information about the pistol, but the question did not contain any info.

If you could make not of any markings on the pistol, it would be helpful.  I can tell you if the pistol is marked 'waffenfabrik Ulm/Do' it is of postwar manufacture.  To tell you more than that, I need the additional info that might appear on the gun.

Thanks for your question...send me a follow up if you like.

Regards,

Doug
