A hard-to-find Winchester No. 42B Sporting Leaf Rear sight for the 1866 carbine, 1873, 1876 rifle and carbine, 1886 (except for the .50/110 Nitro Express), 1892, and 1894 black powder guns. The sight has the correct 8 level indicator on the ladder arms, a middle v-notched movable sight, and a retaining spring. The base attaches through the rear dovetail on the barrel top. This sight was discountined in 1914. A VERY hard to find Winchester sight.
