I still have my Dad's......................from the 50s; it was his off duty gun; and his duty gun when he was a Captain late 60s and 70s.

I've owned a couple of the newer ones but ...... if I grabbed a short barreled revolver it was a 2 1/2" 19/66 or later a 3" 66. So they were eventually used as trade fodder for Smiths.
