These are beautiful examples. I just got a 19-4 that I am very happy with. I also have a well-worn 66-1. I think the model 19 just has the perfect profile for a revolver.
I picked up this M19-4 which dates to the 1978-79 time frame, a while back. It came with mis-matched grips, which really bothered me. Forum member Gun 4 Fun was kind enough to clue me on some key details, such as the football relief and silver washers being the correct style target grip for my gun. I was recently able to find just such a set, here in the classifieds, from forum member Kuglespritz. They arrived, in the mail, today, and I couldn't be more pleased. What a great community and wealth of knowledge we have here. Thanks to all.
On the first page, p0838 posted a 66-1 that had a recessed cylinder but the barrel was not pinned.
Found a 19-4 in the 121K0xx range this weekend. It has a recessed cylinder but the barrel is not pinned and it has a small trademark on the left side of the frame.
Here's a 19-4 that belonged to my Dad. He used to keep it in a leather holster in the trunk of his car. I'd tell him that was a big no-no what with the acids in the leather and western Oregon dampness and all. But what does a kid know? ha ha. It was nothing that a little gun oil and fine steel wool couldn't fix.
