context_page_description: 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 when it was replaced by the Model 520A which ended production in 1948. Stevens also further modified the design when they introduced the streamlined Model 620 in 1927. The Model 620 was internally similar to the Model 520 and was produced until 1939 when it was replaced by the Model 620A which ended production in 1955. This shotgun is a hammerless, pump action, take-down design with a tubular magazine which holds 5 shells.
context_section_description: The redesigned Model 520A was closely related to the Model 520, utilizing the same takedown action and locking breech block.  The receiver lost the distinctive double hump and had a flat top and squared-off back end. The safety was moved to the receiver tang and the trigger housing was redesigned to use a coil mainspring instead of a flat bar mainspring.  The 520A continued to be sold as a store branded gun and under Stevens' budget line Riverside Arms (stamped Model 520).  The 520A was never shown in a Stevens sales publication, it only appeared in Sears & Roebuck and Montgomery Wards catalogs and in Stevens component parts catalogs (the only source where it was identified as a 520A).
  Stevens halted civilian production in 1942 to make weapons for use by the US military during World War II (see Model 520-30 below).  Civilian Model 520A production resumed after World War II, again as store branded guns, and continued until 1948.
