This very rare and attractive Colt New Frontier Revolver is 1 of 25 made by Colt to test the possibility of introducing the .44 magnum caliber New Frontier into the Colt product line. Production was never undertaken, and the prototype revolvers went into the Colt Archive Collection prior to being released for sale to collectors. The factory letter (copy) included with the consecutively numbered experimental prototype advises that these revolvers should not be loaded or fired. It includes a "woodgrain" factory box with a Colt Custom Gun Shop label that matches the gun. The accompanying factory letter (copy) lists this revolver as one of 25 .44 Magnum New Frontier prototypes built by Colt and featuring a 7 1/2 inch barrel, nickel plated non-fluted cylinder with blue finish on the balance and walnut grips. The revolver was shipped to John Keosayian of Chester Heights, Pennsylvania, on August 18, 1999, as part of a 2 gun shipment.
