Hi Al,
Yep it was as they quoted in the brochure a New improved "Twin-lobe" or Impel-action..basically like the wash tub of the Rolls that Mike posted, but square tub instead of round.
The spinner was great to, spinning @ 2850rpm !! and they call it the new "High-G" spin drier..Oooo
There was two dials, one for timing and another for just Spin/heat..very simple, no dial/lever for the pump as it was constantly running..so you would never be able to wash & spin at the same time as the washtub would start to empty as soon as you took the "ball-valve" off the hose to empty the spinner.
Cheers
Keith
