I inherited a Eastern Arms 101-1, 12G, single barrel (30") shotgun. I understand from searching on-line, this is an Iver Johnson gun made for Sears and Roebuck, a "hardware" gun without great value. Stock has some light scratches, metal could use cleaning (bluing?) and stock recoil pad is all dried. I don't believe that it needs parts, except for stock recoil pad that is all dried out. Ideas for restoring at a reasonable price? I've got no gun experience, but I'm very handy. Is there a place to get instructions for taking this single barrel with top level apart? Thanks.
