Great question,
In the golden age of shooting, the 1950s and 1960s, things were much different than today. The big boxes of the time all had there own "store brands" of firearms. Western Auto, Sears, Penneys, and Montgomery Wards were in the gun business, each contracting gun manufactures to produce a specif model for there house brand.
You have a Mossberg 385K bolt action W/polychoke, marketed by Montgomery Wards under there house brand Western Field model 175.
You can find Remington, Winchester, Mossberg, Savage and many more manufactures represented in these house brands.
as a kid I never argued with Mom to go shopping at these big boxes, she could always find me standing next to the gun racks, Pepsi in hand, with visions of Christmas presents to come!
Hope that helps
Good Luck and Stay Safe
