I looked closer to see that it was marked with a stamp 6m and not 10m. I also have the target from the former owner. When he first shoot it to check the zero in Rhein-Main Germany at the Rod and Gun Club there. It looks better then the factory. This Walther is in 99% of new with all paper work and even a new Tin of Match 4,5mm pre 1960 West German Haendler & Natermann pellets, All 3 front and rear sights cleaning rod and wooden ball, Box is in great shape. If any one wood like more pic's please let me know.
And thank you for your help.
