Don't understand the confusion. The major retailers would contract with companies to produce products, including firearms for their private label. Sears sold guns by Winchester, FN, High Standard, Mossberg, and others, all marked with the Sears label. Wards, Penneys, and Western Auto did the same. They also did it with ammunition....Federal produced a lot of ammo for western Auto, for example.
Easy to look at the cross reference at Numrich arms and see who produced what for who.
