I picked this up recently at Cabela's; these are interesting guns I did not know much about. Think about how collectors chase Colt revolvers today, it is difficult to imagine that this gun was a special order in 1956, "made" in January 1957, and did not ship to a dealer until 1964. Sat on a shelf at Colt for over 7 years? After being "special made"? One of a shipment of 4, to a sport shop in Florida that still exists, but is now a gear shop for runners. Between the info from Bev, and a friend that is an old time Colt retiree (out of there 20+ years), I learned that all the 2" RB OPs were special orders. Some in all bright blue, some in duo tone blue, a tiny number in nickel.....all were "one off" made guns. You may find them with checkered triggers (not this one), checkered cylinder latches (yes on this one) and non-standard hammers (yes on this one). I still cannot get over these being made, and put on a shelf for 7+ years. Probably sold new for $50-60 too. Things sure have changed....
