GE Upright
That design dates to the early 1960's, GE's only vertical motor upright, and it was made into the 1970's with the Premier name.
The white levers are suction control, and tool conversion. The suction lever opened a bleeder in the nozzle so it would not hug the carpet. The other lever was hose conversion. It shifted the suction from the nozzle to the hose port, and shifted the motor into high speed. The hose connected at the right rear of the base.
These were ok cleaners, but very LOUD! The sounded sorta Kirby-ish, but had a very distinct whine.
Nice Find Greg!
