It will be marked on the barrel, but that should be a 12 g shotgun.
Probably 1970's. Made by Savage for Sears. Value around $250.
A Model 37 is a "pump", so a double barrel could not be a Model 37
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.
