Our Assessment: The Stevens Model 520 was a pump-action shotgun developed by John Browning and originally manufactured by the J Stevens Arms & Tool Company between 1909 and 1916. Stevens was sold to New England Westinghouse on 28 May 1915 and production of civilian firearms was greatly reduced. The company was renamed the “J Stevens Arms Company” on 1 July 1916 and New England Westinghouse used their manufacturing facility in Chicopee Falls, MA to produce Mosin-Nagant rifles under contract for the Russian Czar during World War I. After the war, Stevens was sold to Savage Arms on 1 April 1920 and full production of civilian firearms resumed. Under Savage ownership, Model 520 production continued until 1939. The military model was designated the 520-30 and was made in trench, riot, and aerial training configurations. After WWII the model was standardized and saw use through Korea into the Vietnam War and was used by law enforcement after its military service. This example has some scattered cosmetic wear, it rates in about Very Good condition and functions smoothly. Please see our photos and good luck!
