Springfield Arms shotguns were manufactured by the Stevens division of Savage Arms from 1920 to 1948.
Built c. 1930-1948 by Stevens division of Savage Arms. If in useable condition, possibly worth $200+.
the stevans/savage double barrel 503a was made between 1936 and 1954
The Springfield line was sold by Stevens/Savage from about 1920 until the 1940's. If you need a closer estimate of the age, you can get the Stevens Historian's address from savagearms.com and send him $15 and the serial number.
First you have to determine what kind of "Springfield" you have. It could be a US military arm from the Springfield Armory dating to sometime before the Civil War or a new sporting arm from Springfield, Inc., but most likely it is a shotgun made by J. Stevens Arms or the Stevens Division of Savage Arms.
