I have a Walther ppk that my father brought back from WWII. He said that he took it off a German Officer. It has a swastika and an eagle imprinted on the frame of the gun. It is in good condition. Anyone have any idea of this gun's value?

Avid gun collectors and/or WWII collectible nuts would love this gun. Suggest you take it to either a reputable gun dealer or antique dealer or a local gun show to get the value of this. It is a real collectible.

Depending on exact models there were WWII era with selling prices of 4800.
Of course the value of what it meant to your father and family is priceless.

For insurance value, have a dealer give you a written value
