An ORIGINAL Winchester No 24 depressedFlat Top SPORTING REAR SIGHT. These sights were removed from Winchester Sporting rifles and were the standard factory issued sight on Winchester lever-action rifles. The sight has a flat-top configuration that is not straight across, but slightly depressed, with one sighting notch in the middle, and on the bottom there is a set screw. Bluing still strong and sights in excellent condition. The early elevator (st40 or st117 wop) is correct for this rear sight.
