I believe that your Sears shotgun is a Winchester model 37A shotgun that was made for Sears Roebuck And Co,.
It depends on the the number of barrels, year, model, condition and serial number.
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.

Check the receiver and barrel.
Tell us a little more. Sears sold a lot of different shotguns and a serial number will not identify it.
410 is not a gauge. 410ga
on the receiver Serial numbers were not required on longarms prior to 1969 and most of the manufacturers of utility and 'catalog store' guns did not use them.
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.
