Sights like these are typically what would have been used on the Winchester High Wall target rifles as well as various lever action Winchester models with this example being for the desirable model 1876 and so marked, "76" under base. This set consists of a mid-range vernier rear sight that has a fixed base and is adjustable for elevation only. The side of the staff is graduated from "0-75" and is equipped with an eye-cup. This set also has an original Winchester wind gauge front sight that is laterally adjustable and is also equipped with a spirit level on the back side. The front sight is complete with five different inserts. The complete sight set is stored in an original black leatherette Winchester case which has a lid marked "WINCHESTER/MID-RANGE/VERNIER/AND/WIND GAUGE /SIGHTS."
