Appears to be a custom made copy of a Colt Model 1883 Gatling gun with six revolving barrels and a plaque on the action marked "GATLING'S PATENT/MODEL OF 1883/COLT'S PATENT FIRE ARMS/NEW YORK CITY, NEW YORK U.S.A./SERIAL NO. 440". The mechanism appears functional when the handle is cranked. Includes a metal pedestal style stand and one magazine.
