If the GE/Premier is NOT a fit !
I remember someone in the family having a Kenmore upright in the early 50's. That had a vertical belt drive. Like a Royal or a Kirby. I was a modern looking upright. Long short Hood, sort of like a Hoover 28 hood. Then a wide front, where the brush roll is narrowing back to the bag and Handle. It had a head light, and
a metal plate that you removed under the headlight. For belt changes or attachment connection. The machine was very powerfull, with a gray cloth bag. Two
tone body and dark gray hood.
Now I do remember the Hose being burgandy for some reason, with 2 metal wands. floor brush, with a slide in upholstery tool, with a swivel connection. For two different brushs. Much like another Aunts Gray Kenmore Torpedo cyclinder Vac. from the late 40's also.
It could be a short set sold with the Kenmore as well. The gray color just seems
more likely to be Kenmore.
I could be completely wrong !
