What is the value of a Crescent Firearm double barrel shotgun marked only Crescent Firearms Co Norwich Ct USA and no other model number or any detail?

If it's a hammerless boxlock, it could still be a shooter worth $100 - $250. If it has large side hammers, it's a wall decoration but still worth almost as much. I have one... it belonged to my dad...he purchased it used around1918- 1920 SN 410344 stamper on the stock/receiver, barrel and the hand grip, (same numbers on all three pieces) ... Does this mean anytrhing to anyone??? Mdales Only to you. There is no serialization listing for Crescent firearms that would allow you to date its manufacturer.
