== == "Riverside" was a brand model shotgun produced by the J. Stevens Co. (which was bought out by Savage in 1920) - These were utility grade double barrel shotguns manufactured between 1877 and 1988. If the serial number is prefixed with a letter it was manufactured after 1949. If there is no letter, it was manufactured prior to that. Thats the best I can do.
Sold by Sears Roebuck. Probably manufactured by Stevens.
The Stevens model 311 was discontinued in the year 1989.You would have to contact Savage/Stevens to get the actual age of your double barrel shotgun.
"Your" Winchester Model 21 Double Barrel Shotgun was manufactured in 1933, giving it an age of 77 years, as of 2010.
If it is side-by-side, probably Stevens.
Hunter Arms Company, Fulton, New York
there is a model 311a double barrel shotgun made by Stevens/savage but have not heard of just an 11a. I have a 20ga 311a given to me by my grandpa and he said it was made in the fifties. You can go to Google and type in Stevens model 311 and will pull up information on this shotgun.AnswerRemington made a model 11a but it was not a double barrel it was a semiauto.
Springfield Arms shotguns were manufactured by the Stevens division of Savage Arms from 1920 to 1948.
You may have to break the shotgun down in to the barrel section and the receiver section first.Look under the barrel section on the flat just ahead of the lug for the serial number.
