Sears guns with the Eastern Arms label were made by Andrew Fyrberg, Iver Johnson, and J. Stevens. If you're lucky, your gun will be one of the Stevens guns and parts MAY be available from Savage Arms or Numrich Gun Parts.
If it is marked "J. Stevens Arms & Tool Co" it was made between 1886 and 1916 when "Arms & Tool" were part of the company name. Value will depend on the configuration and condition. Side hammers usually go as mantle decorations, especially if they have damascus barrels ($75 for single shots, $125-$150 for double barrels). Boxlocks (back hammer or hammerless) in good shape can bring $75 (single) to $250 (double) as shooters.
