Originally known as the “Improved Henry” for its side loading gate, the 1866 model earned the nickname “Yellow Boy” for its brass frame. Cimarron’s 1866 Yellowboy Short Rifle pairs that historic design with a 20-inch octagon barrel, a blued finish and a walnut stock. This example is chambered for .45 Long Colt and is built for traditional sporting use and historical shooting disciplines.
