Manufactured in 1977, 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, and Karl Furr and Paul Kuhni's markings are on the underside of the gear box along with the 1972 production date. The gun is installed on a mostly brass carriage with traverse and elevation adjustment equipment, a pair of on-board magazine storage boxes (one of which contains an extra Accles pattern magazine), and dismountable wheels. Matching exterior numbers are present throughout.
