Union Metallic Cartridge Company
In 1854, Jacob Schuyler, Marcellus Hartley and Malcomb Graham formed the Schuyler, Hartley & Graham Sporting Goods Company in New York City. Destined to become one of the largest sporting goods houses in the world, it provided cartridges and rifles produced by other manufacturers to the Union Army during the Civil War and amassed a fortune. In 1866, the company acquired two small cartridge companies, and the following year re-incorporated as the Union Metallic Cartridge Company (UMC) in Bridgeport, Connecticut. By 1900, Hartley was the sole owner of the company.
U.M.C. known as the Union Metallic Cartridge Company was founded in 1867 by Marcellus Hartley in Bridgeport, Connecticut. They manufactured a variety of shells up until 1911 at which time the company was merged with Remington.
