I believe that your Sears shotgun is a Winchester model 37A shotgun that was made for Sears Roebuck And Co,.
Your local gunsmith may be able to clarify whether or not Winchester actually manufactured that shotgun for Sears.

Winchester 1200
Winchester, same as model 1400.
I believe at one time,. Winchester made a model for sears. I had a sears M200 20 gauge and it was made exactly like my Winchester Modell 1300 ranger,.. very, very similar.
The Sears Ted Williams Model 300, semi-auto, shotguns were made by Winchester. The Sears 300 is the same as the Winchester Model 1400.
Stamped on the receiver and probably the barrels, too.
The Sears Ranger 105-20 16 gauge shotgun came out in the 1930s. The Sears Ranger shotgun has a 26-inch barrel.
The Sears 200 is a Winchester Model 1200 with some minor modifications. Winchester 1200 of the same gauge will fit the Model 200 receiver. Buttstock and trigger group will not interchange.
That will depend on the Model of shotgun you are asking about,along with the overall condition of your Winchester shotgun?
