Over the past 100 years, many makers have made double barrel 410 shotguns. Provide a detailed description of ALL markings, barrel length, finish,etc., and some one might be able to help you.
The gun was made around the turn of the century(1900).

The name and address of you 410 should be printed on the barrell of you firearm.
Made around the turn of/early part of the century.
I would look at the number of barrels. If there is more than one barrel, you know you have at least a double barrel shotgun. If there are 1 or less barrels, then you don't.
There is no way to determine the gauge without seeing the gun. Assuming it is one of the standard gauges, you can measure the inside of the barrel. 12 gauge is .729", 16 is .662, 20 is .615, and a 410 is .410.
Gun store, auction sites, pawn shop, local ads.

I believe that the Plymouth side by sides were made by Cresent Firearms.
The Stevens Model 22/410 was made from 1939 to about 1950, when the gun became the Savage Model 24. In poor shape, it's worth maybe $125, in average shape between $200 and $300, and in great shape between $300 and $450 or $500. Condition means a lot to determine value.
You have a winner! The .410 is a rather rare gun. Worth $5-$600 if in excellent shape.
