I believe that your Sears shotgun is a Winchester model 37A shotgun that was made for Sears Roebuck And Co,.
$25
The Sears Roebuck Model 20 12 gauge shotgun, serial number 5832006 is valued at $200 in very good condition. It good condition, it is valued at $125.
You would have to list the model number of your shotgun,to identify the maker of your sears and roebuck shotgun,in order to get the correct buttstock.
