Hello all, I am looking for help to date my newly accuired 17-4 .22lr revolver. I got it with box, papers, cleaning kit except the cleaning rod. I got the wire brush, screwdriver and swab. The serial # is 22K75xx. It has recessed chambers and pinned 8 3/8" barrel. If anybody has or knows where to get the cleaning rod I would truely like to get one. I shot it yesterday and very happy with the results. Great site and thank you for the help.
