Posting this or a friend who owns a shop locally, this gun strolled in not long ago and he purchased it. It’s a Walther PPK chambered in 22, serialized on both the slide and frame with 2 mags numbered to the pistol in the side of the base plate.
Sights are painted, rear is red front is white, could this be a Walther bank gun or other Military/ Police contract?
These were issued to German bank employees with an interesting holster. I'm sorry to say I don't have any pictures handy of one.
One of my Walther reference books may have a picture or two. If I think about it I'll try to find some pics and post in the thread.
