The bad news is that I'm having the same difficulty as you. The good news is that A.J.Stevens was bought by Savage in the early 1960's.
The J. Stevens Company was bought by Savage Arms in 1920. The Springfield name was used from about 1930 to 1948.
The patent was dated April 17, 1894. There were no cartridge arms in in 1794, in fact, the percussion system had yet to be invented. J. Stevens and Company was formed in 1864 and used that name until 1886 when the name was changed to J. Stevens Arms and Tool Company. The plant was sold to New England Westinghouse in 1916 and used to produce military rifles for the US and the Soviet Union. In 1920, Savage purchased the facilities and manufactured firearms with the name J. Stevens Arms Company until about 1948. Guns produced after that date were marked with just "Stevens" until the name was discontinued by Savage in 1991. Many Stevens guns were not serialized, so they can only be "dated" to the period of production. I believe that Mr Callahan charges $25 to research a Stevens firearm.
I have had mine since 1965.
No way to know without a sn. If no sn, no way to know.
Only made from 1969-1972.
My Springfield model 83 ( J Stevens) is stamped 22 Short, Long and Long Rifle on Barrel. If yours is as well, then yes, it would fire LR rounds.
Its hard to say what the exact age and/or value would be. J. Stevens Arms Co. began producing the Model 15 springfield in 1938. It retailed in the Sears and Roebuck catalogue for $3.18. In really good condition it is probably worth about $100.
The Springfield Model 84 was made by J. Stevens Arms Company, Chicopee, Mass.
The Springfield name was used by Stevens from 1920 to 1948.
The Springfield Model 15 was produced by The J. Stevens Company beginning in 1938. Intended as a boy's rifle (A low-caliber, easily used, rifle), it saw production into the early 40's when production tapered off on account of the war effort.
Stevens Model 56 Made 1933 till 1945, 97,500 made. from Gun Trader.
