I have a chance to buy an all matching late war commericial Walther PP with ac marked frame. Pistol has 99% metal finish, 2 matching mint mags, and a mint black PP holster. Whittington's vol 2 states that approximatly 1700 were produced. I was wondering what a fair price range for such a rig would be? I am asking because I have no experience with PP's, and I have never saw this variation for sale to allow me to judge the value.
