The Rough Riders, officially the 1st U.S. Volunteer Cavalry, are the most famous of all U.S. units from the Spanish-American War and are particularly well-known for being led by future president Theodore Roosevelt during their charge up Kettle Hill during the Battle of San Juan Hill. The letter from John Kopec and included National Archives letter indicates this revolver is recorded as issued to the "1st U.S.V. Cavalry" on June 20, 1898 and then issued to Private Horton A. Bennett of Tularosa, New Mexico Territory. Bennett transferred from Troop H to Troop I of the Rough Riders on May 12, 1898. He was a 27 year old cowboy born in Jack County, Texas. He mustered out at Camp Wikoff on Long Island on July 31, 1898. Bennet was also issued a Krag carbine (sn 27044) that was later sold out of the Raritan Arsenal in 1922. Copies of his muster rolls are included. This revolver was originally manufactured in 1874 and is identified in the included factory letter using the frame serial number as one of 400 refurbished by Colt and delivered to the inspector at the factory on January 31, 1896. It was converted from a "Cavalry Model" to an "Artillery Model" at that time by fitting a 5 1/2 inch barrel in place of the original 7 1/2 inch barrel. While most of the revolvers refurbished by Colt retained matching serial numbers, like most of the converted revolvers, the serial numbers are mixed on this revolver. Kopec theorized the revolver may have been refurbished a second time following its use by the Rough Riders, possibly at the Manila Arsenal which would explain the mixed numbers and possibly the blued finish on the frame. He suspected the barrel was replaced again at a later date. It has a partial serial number starting with "1" and probably ending in "3" or "8." No address is visible on top, and a "P" is on the bottom. Kopec believes this barrel came of another 1896 Colt refurbished revolver. The frame is numbered "4238" and has the two-line patent marking and "U.S." on the left side. The trigger guard is also from an 1874 manufactured Cavalry Model and has "4041" and a small "A" sub-inspection mark from Ainsworth. Kopec indicates the nearest revolver in the National Archive records was issued to Company C of the 8th Cavalry. The cylinder appears to have the partial serial number "377" or "877" and a "P" proof. Kopec noted the small locking notches suggest it was probably off an 1873 or 1874 production Cavalry revolver. The back strap has no visible markings. The hammer is from c. 1906-1910. The grip has "1901" on the left and Rinaldo A. Carr and Odus C. Horney cartouches. The custom display case has a H.W. Sakschek collection seal and display label noting the use by Bennet inside the lid, a "U.S." marked compass, U.S. medal, key hanging from a chain on a Theodore Roosevelt medallion, cartridge block with six cartridges, and an L-shaped screwdriver.
