Does the label give an indication of the company who made it? Obviously, it's based on the Frantz Premier, which was Jim Kirby's first production model vacuum cleaner. In 1918, GE bought Frantz Premier. Frantz Premier then became Apex. Wondering if it was made by GE (the "new" Premier) or Frantz?
The label states Manufactured For Eclipse Machine Company in Sidney,Ohio. There is a key on the underside of it that when turned releases the nozzle. I assume its a hookup for attachments or something.
