== == "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.
Stevens/Savage used the Riverside name from about 1920 to 1945.
Can't give you an exact date, but Stevens used the Riverside name from about 1920-1945 according to my notes.

The value of a Continental Arms company 20 gauge shotgun is dependent upon a number of factors. The age and condition of the shotgun would need to be considered when determining the value.
It was made sometime between 1920 and 1948. If you really need to know more precisely, find the contact information for Mr John Callahan on savagearms.com. For a fee he will research old Stevens guns. (Riverside is a Stevens trade name).
