This K22 belongs to a good friend. S/N K 2539XX. Can you tell me the approx manufacture date?
Under the yoke, there is no model but the number 13384. The S/N -without the “K”- also appears in the barrel under the extraction rod, and the cylinder, something I’ve never seen before. Any comments about these unusual (to me) numbers/locations? Please see pics.
Thanks for your help, and Happy New Year to all!!
