This is a full scale functional muzzleloading cannon made to resemble a Hotchkiss Model 1875 mountain gun; a breech loading gun originally designed by Benjamin B. Hotchkiss and used by the U.S. Army during the American Indian Wars, Spanish-American War and Philippine-American War. The tube appears to be made of iron, the right side trunnion is marked "03" with no other visible markings on the tube, with a blade sight at the right center area of the tube, adjustable post rear sight, and an open touch hole on top. The iron carriage has an oval brass plaque on top that reads "HOTCHKISS' PATENT/PARIS*1885" around a "1". The tube measures approximately 45 inches, with a 39 inch inside bore length, with overall measurements including the carriage approximately 77 inches long by 41 inches wide by 39 inches tall.
