Re Whirlpool
Whirlpool got the vacuum business from a Sears deal...Sears engeneered a hostile takeover of Birtman electric company and Seeger refrigerator company in 1957, this got their vacuum and mixer business as well as Coldspot business under 1 manufacturer..the Birtman built Kenmore vacuums have a odd looking motor built by Birtman, when this took over, they sold off the mixer business to Hamilton Beach, thus the 116 prefix, gave way to a 400 prefix, denoting HB, if you look at a Kenmore vacuum closely, somewhere you will find FSP stamped on it....Factory Specified Part = Whirlpool.Somewhere around the same late 50s timeframe, Whirlpool bought out Servel to get the ice maker, thus Coldspots had icemakers fairly early.
