You posted this under the Iver Johnson topic and that company made a lot of revolvers in Fitchburg, which isn't far from Chicopee Falls. The only arms maker I find in Chicopee is Stevens, but I have no records of a Stevens revolver. Are you sure it is not a tip-up pistol?
Springfield Arms shotguns were manufactured by the Stevens division of Savage Arms from 1920 to 1948.
We have had(stevens savagen arms corporation USA Chicopee falls mass) for more than 3 generatins.My grandfather has bought it. It is still active.Thin and severe.
Although the company dates back to 1864, the name "J Stevens Arms Co" was not used until after the company was bought by Savage Arms in 1920. In the mid 1940s, the name was shortened to "Stevens".
Massachusetts Arms Company: Trade name used by J. Stevens Arms and Tool Company on firearms for Blish, Mizet and Silliman Hardware Company of Atchinson, KS. The name is also attributed to Crescent Firearms, but a single shot with a Chicopee Falls address is almost certainly a Stevens.
The Springfield Model 84 was made by J. Stevens Arms Company, Chicopee, Mass.
this is a misprint. It should be a model 75 rather than a 57 as it appears in the question.
Sometime between 1920 and 1948.
According to the stevens reference files the gun was made between 1936 - 1945, approximately 100,000 were made. As far as value?
About 1886, if the marking is J. Stevens Arms & Tool Co.
