The home of Electrolux!
Got it.
The Electrolux Corporation was located in Old Greenwich, Connecticut. The factory was beside the railroad track that went between New York, and Boston. Originally this was the Dalton lathe and tool company, then it was the Welte Tripp organ company (pipe organs), finally, in 1932 it became Electrolux. The model XXX (30) was the first all American made Electrolux. Prior to that they were made in Seeden.
As for Wallingford, this is where the school, Choate/Rosemary Hall is located. When I was a kid my grandpa bought all the vacuum cleaners for Choate. They were Electrolux and Kirby.
