Thanks so much for this! What an enlightening article!
So cool to read that the famous Eureka Williams "E" logo was called the "flying E"!
Nice to learn the name of a Eureka engineer, and the name of the company that supplied the braided hoses for the company.
Indeed, this little turtle-shaped vac was also sold under a variety of department store brandnames such as Viking and Baycrest and Beaumark in Canada, and Wards and JCPenney in the USA. I think there was even a Wizard version for Western Auto.
Funny...I always thought the Eureka 1960's blue was turquoise! Now I learn that it is called lagoon blue!!
