Lee-Enfield No. 4 Mk. I* SN 31C7081 Marked "S" to show it was made by Stevens - Savage in the USA for British use but not marked "U.S. PROPERTY" as most were. Sporterized later. In the U.S. over a million No. 4 Mark I* Rifles were made by the Savage Arms Company. This Company incorporated the Stevens Arms Company and, to distinguish weapons of Stevens manufacture, the letter “C” was included in their serial numbers. The “C” denoted Chicopee Falls, Mass., the location of the Stevens factory. All the No. 4 Rifles made in the U.S. were marked “U.S. Property” on the left side of the body, and they were the only ones to be fitted with barrels embodying six-grooved rifling. In 1942 a small number were converted at Enfield (U.K.) into Sniper Equipments.
