According to its serial number and the mentioned list, 1986 is a good guess as the year of manufacture for your PPK. It was made by Ranger and sold by Interarms. The correct German calibre desgination is 9mm kurz.
Hello how are you, I thank you, that's right, it was a "finger" error, I thank you very much.
I appreciate your information, after Marurhin (in France) was Ranger (in USA) who made them for how long in the USA, and was Interarms who distributed? The model I showed you is still very reliable, I imagine since it had all the specifications of Carl Walther's signature? I have another from 1966 made in Germany, my question is whether in steels, the finished or the mechanism have any difference with the one made in 1986 ??
