An ORIGINAL Winchester Factory issue No 22G Sporting Rear Sight. These sights were removed from a variety of older pre-64 Winchester rifles, including Model 70, 1892 Sporting rifles, 1894 carbines (if your dovetail is 4 inches from receiver), and models 54 and 1895 Winchester rifles. The sight is a semi-buckhorn configuration with a screw hole in the back. The sight will need a smalladjustable scew and the adjustable V-notch in the middle. Bluing still strong and sights are in excellent condition. The elevators (st197 wop or st23) are correct for this rear sight.
