I just got a hold of a K 22, a revolver that I have wanted for a great many years. Can anyone tell me how old it is? It is marked on the butt K 46668 and on the inside of the grips. It's a six inch barrel, and has about 80 % blue with just a few freckles of rust starting. It has never been apart until I cleaned it last night. It has a small part in the frame behind the trigger that apears to limit the overtravel of the trigger. Can't wait to give the old girl a try. Many thanks, the toolman.
