This revolver is identified in Kopec and Fenn's "Cavalry & Artillery Revolvers…a Continuing Study" on page 111 by serial number as issued to the famed 1st U.S.V. Cavalry (Rough Riders), specifically to Michael Hogan and William W. O'Dell, both of Co. I, during the Spanish-American War. Includes a John Kopec gold-seal letter of authentication, awarded to “a revolver which is found to be authentic in every respect, regardless of the percent of original finish remaining.” This letter confirms that this revolver was issued to the two Rough Riders mentioned above and “the reason of this double recorded issue is unknown at this time.” Kopec concludes, “In looking over this very nice ‘untouched’ 1896 Artillery revolver we have noted its fine condition…We have truly enjoyed reviewing this outstanding ‘1896’ documented ‘Rough Rider’ Artillery revolver.

Fine as Colt refurbished to artillery configuration. The revolver retains 60% factory blue finish with muzzle and high edge wear, some minor pitting on the muzzle end of the barrel, some light spotting is visible on the cylinder and the balance thinning to a spotty gray patina. The frame shows 30% darkened case colors with a smooth silver/gray patina on the balance. The grip is also fine with some scattered minor dings. The markings are crisp and clear. The action is excellent.
