10/26/21 - This is an original Walther conversion kit for a 9mm Walther PPK. The kit is complete and converts the pistol to a 4mm practice rounds. Includes approximately, one hundred, 4mm rounds and original instruction manual. All parts are original and excellent, as shown. Minor pitting in the barrel, but the rifling is strong. The box is in great condition as well with minor tearing and use wear. A great addition for a Walther collection.
