Estate Range Co.
The following information is from Lane Public Lib. in Hamilton, OH and other sources. In 1955, Estate (the cooking appliance division of RCA) merged with Seeger Refrigeration, Sears Roebuck & Co., and Whirlpool Corp. The resulting company was known as Whirlpool-Seeger Corp. At this time they received a license from RCA to use their trademark for a certain number of years on their appliances. Sears is included due to their substantial ownership in both Seeger and Whirlpool.
Whirlpool announced in early June of 1961 that production at the Hamilton plant would end by June of that year.
