Originally known as the "Improved Henry" due to its patented loading gate on the side of the frame, the 1866 model was known as the "Yellow Boy" by the Native Americans, because of its brass frame. Cimarron offers several 1866 Yellowboys, such as this 20-inch barreled Short Rifle with an octagon barrel. Caliber is the .45 Colt with blued barrel.
