Just received a Walther PP from a friend who's husband just passed. Don't have a clue about these pistols. Carl Walther Waffenfabrik Ulm/Do. Model PP 9mm kurz. Made in West Germany right under the mag release. Nazi eagle Crest stamped in several places. The serial # is 24505 A. On both grip frame and slide. Anyone might know when it was manufactured? Value? It's in excellent condition. No pitting or rust anywhere. The grips are excellent as well. Blueing also in great shape. Thanks for any help.
