With such a detailed description of your shotgun, all I can say is that Sears sold shotguns, including .410 gauge, from the 1880's to about 1990.
The value of the 410 Sears and Roebuck JC Higgins Model 101 shotgun varies greatly with its condition. In excellent condition the gun retails for about 250 dollars or so.

about $100
The Sears Roebuck model 410 103.741 is a shotgun that was produced in the early 1960s. Specifically, it was manufactured around 1964. The model number indicates it was part of Sears' line of firearms, which were often made by other manufacturers and sold under the Sears brand.
I believe that your Sears shotgun is a Winchester model 37A shotgun that was made for Sears Roebuck And Co,.
