This scope is a historic 5-power telescopic sight introduced by the Winchester Repeating Arms Co. in 1910. It became famous as the U.S. Marine Corps' primary sniper and target competition scope on M1903 Springfield rifles during World War I, later seeing action in early WWII Pacific campaigns. This scope is in excellent condition with a nice blue finish and fire blue finish on some parts. Has Scope ring mounts. The reticle is visible and optics are clear.
