It was manufactured by J Stevens between 1920 and 1948. There should also be a model number on the right side - probably 5000, 5100, or 311. Value will be $150 to $250, depending on condition.

Riverside Arms was a tradename used by Stevens and later by Savage. Would help to know what other markings are on the gun.
What is my 12 gauge dated oct 20 1915 from riverside arms in Chicopee mass. Worth. Number 48780.
I too have a Ranger .410 sxs hamerless shotgun. I believe it to be made by Stevens. Possibly a model 311.
It would have been made by Stevens/Savage between 1920 and 1948. Might be worth $75 on a good day.
It sounds as if you have a Ithaca Crass model shotgun,that was produced in the year 1903 by your serial number.
About $75 to $100, retail. sales@countrygunsmith.net
I have a 12ga Chicopee Arms shotgun that I inherited from my father. "Chicopee Arms" is a brand name used by the H.D. Folsom Company for selling hunting shotguns in the 1940s. Hope this helps!
Try your local gunsmith. The Riverside is a Stevens shotgun. If you can find out which model it is, you can probably find the wood at Numrich Gunparts
