My mom and I picked this up yesterday at a pawn shop for $450. I know a little about Walther guns and this one is somewhat special because it was made in West Germany. Can someone please tell me what year this gun was made? And is my mom and I got a good deal? I've attached some images...

Ok well so far no luck with a PPK in .32 so I am now looking for a PPK in .380 ACP. Searching for W. German made so preferably 68' or earlier manufacture but will consider W. German Interarms models. OK with a wide range of conditions. Cash money. Thanks to everyone in advance.

EDIT: I found and purchased a PPK. No longer want to buy. Thanks I've been trying to buy a blued Walther PPK for about five months without success. Any idea where I can purchase one? I've checked my local gun stores, GunsAmerica, GunBrokers, and CheaperThanDirt. Desired specifications...
