I've show it before, but given any opportunity I will show it again: an early CM from before the model number era -- K101707 (1951).
Now that I have seen the attractive specimens of 2" Model 15s in this thread, I'm going to have to keep an eye out for one. I have a postwar K-frame snubnose from 1947, but it would be really cool to have a specimen with adjustable sights.
