This is an exceptional example of one of the approximately 2,800 scopes developed and manufactured c. 1940 for the U.S. Marine Corps, to be installed on 1903 National Match rifles by U.S.M.C./Navy armorers (a combination also known as the "U.S.M.C. 1941 Sniper"). The scopes themselves were kept in inventory after World War II, seeing re-issuance as late as Vietnam. It is marked "J. Unertl/USMC-SNIPER/1671" on the main body tube ahead of "8", with a rail-guided sliding aluminum front ring and an adjustable Unertl marked rear ring. Includes an unmarked period box. Provenance: The Steven Preston Military Collection

Excellent, retaining 98% original blue finish on the scope body with a few scattered very small patches of light corrosion, and crisp optics. The rings retain 98% original anodized finish. Included box is very good with moderate edge wear and light aging. A must have accessory for the serious U.S. Military collector.
