Manufactured in 1971, this is a 1/3 scale functional copy of the Colt/Gatling Model 1883. An evolution of Richard Gatling's original 1862 design, the 1883 Gatling integrates a full brass housing from the barrel group, which protects the mechanism from debris, sea spray, and other hazards, as well as the Accles pattern magazine, a donut-shaped drum with on-board drive rotor, which allows for higher and more consistent rates of fire than the gravity-fed magazines of earlier models. Overall measurements are 21 inches tall, 29 inches long and 23 inches across. The top of the body bears a reproduction of the original Colt/Gatling markings, with a set of elevation adjustable sights on either side, a set of cosmetic spirit levels, and Karl Furr and Paul Kuhni's markings are on the underside of the gear box. The gun is installed on a steel and brass carriage with traverse and elevation adjustment equipment, a pair of on-board magazine storage boxes, and dismountable wheels. Matching exterior numbers are present throughout.
