The Uberti 1866 Flatside 150th Anniversary Yellowboy Rifle Brass 356125 is a masterful reproduction of the legendary Winchester Model 1866, chambered in .45 Colt. This special 150th Anniversary edition celebrates one of the most iconic lever-action rifles in American history, affectionately nicknamed the “Yellowboy” due to its brilliant brass frame. Uberti’s faithful recreation combines historical accuracy with modern manufacturing precision, making it a prized piece for collectors, shooters, and fans of frontier firearms.
Historical Significance of the Yellowboy
At the conclusion of the Civil War, Oliver Winchester and his team sought to improve the Henry rifle, resulting in the Model 1866. Superintendent Nelson King introduced a practical loading gate that replaced the Henry’s split-tube magazine, enabling faster, safer loading and the addition of a wooden fore-end. The Model 1866 quickly became popular among lawmen, cowboys, and Native Americans throughout the American West. Beyond the United States, the rifle saw service internationally: Benito Juarez’s forces in Mexico used the Yellowboy, and Turkish troops employed it during conflicts with the Russians in the 1870s.
Design and Craftsmanship
Uberti’s 1866 Yellowboy faithfully reproduces the historic Flatside design in a Short Rifle configuration with a 20-inch octagonal barrel. The brass frame gleams with authenticity, complemented by a blued steel barrel and case-hardened lever. A-grade walnut stock and fore-end provide a classic look and comfortable handling, while the brass crescent buttplate completes the traditional Old West appearance. Each component has been crafted to reflect the attention to detail and rugged reliability that made the original Yellowboy legendary.
