Manufactured in 1880 as a Fourth Model 1866 rifle with the gradually sloped receiver in front of the hammer and the serial number on the bottom of the lower tang in script numerals. These rifles are one of the most iconic weapons of the American West with this example having made it to England, proving that the Model 1866 had international appeal. The direct descendant of the iconic Henry rifle, they bridged the gap between the Henry and the Winchester Model 1873. The Model 1866 was highly prized on the western frontier for its rapid firepower in comparison to many single shot arms of the time, and was used by people in all walks of life. The top of the barrel is marked with the standard two-line Winchester address and King's patent marking. London proofs are stamped on the left side of the barrel and receiver at the breech. The cartridge elevator is marked "44 CAL." It is fitted with a German silver blade front sight and a later production replacement elevation adjustable notch rear sight. It is mounted with a smooth forearm and straight grip stock with an iron trapdoor crescent buttplate (cleaning rod not included).
