This is a very rare and unique Colt New Frontier revolver that, according to the included letter from the Colt Office of the Historian, is 1 of 25 made by Colt "to determine the feasibility of introducing the .44 magnum caliber New Frontier revolver to the Colt product line." Unfortunately, production of this revolver was not undertaken and the prototypes went into the Colt Archive Collection. Luckily, the prototypes were made available for sale as a unique addition to any Colt collection. Colt advises that this revolver should not be loaded or fired. It has a fixed ramp front sight and adjustable rear sight with "COLT NEW FRONTIER S.A.A. .44 MAGNUM" on the left side of the barrel and the one-line address on top. The two-line/three-date patent information is on the left side of the frame followed by the Rampant Colt. It is fitted with a nickel plated, non-fluted cylinder, and smooth walnut grips with gold Colt medallions. It includes a "woodgrain" factory box with a Colt Custom Gun Shop label that matches the gun.
