Duane, to the best of my knowledge all Coldspot refrigerators in that time period were made by Whirlpool, in their Evansville, IN plant. I'm thinking some later models (Kenmore) were made by GE, but don't think Frigidaire ever made refrigerators for Sears. A good friend of my mom's owned a Sears "catalog merchant" store in the 70's, and got to visit vendors factories occasionally. She was to the Whirlpool plant in Evansville more than once, and also to their factories in Clyde (washers) and Marion (dryers) OH. I remember her telling us that Whirlpool was Sears most important vendor, and that Sears owned majority stock of the company at the time.
