An ORIGINAL Winchester Factory issue No 22E SPORTING REAR SIGHT. These sights are very rare as they were only produced for a short period of time, starting in 1924 with production being abandoned in 1931. These sights were placed on a variety of older pre-64 Winchester rifles, including the 1866, 1873, 1886, 1892, 1894 Sporting rifles, 1894 carbines, and also models 53, 54, and 55 Winchesters. The sight is almost a full-buckhorn configuration with bluing still strong and sights have serrated or smooth edges on the outside of the buckhorn. The early elevator (st122 wop) is correct for this rear sight.
