Hi Electroluxxxx:
You must be talking about the Lux Company of Stockholm, Sweden, which figures into my history. And your information is 100% accurate. However, I'd prefer to talk to you about this privately.
In 1979, I had limited data, and that was why the patent books were so vital. Basically, these were a collection of patents on vacuum cleaner prototypes, and parts, from motors to attachments that I acquired from the Research department of the Chicago Public Library. Through these I saw parts and could build the history of the machines. A patent search was like a crossword puzzle. Somebody working for Electrolux may show up in Kirby, or Hoover. Far too complicated to go into here. The Electrolux model LX was years in development, and the prototypes were quite amusing.
As I've said repeatedly, I first watched the model LX eject when I was between two and three years old, and it made a lasting impression. The rest, as they say, is history.
