That looks like the model WW front loader I purchased in 1982.
It worked well and I liked it very much. However, it did have a few downsides:
sometimes it did tangle clothes, as the tub never reversed direction.
it tended to get out-of-balance, sometimes, during spin
Had the most unimaginabley loud spin solenoid. When somone was standing next to the machine when the spin solenoid engaged, they usually visibly jumped (including me)! This feature actually caused more fun than annoyance, if you could get an unsuspecting observing to stand next to the machine right before the spin cycle. Hehe
Advantages:
Was a cool looking machine
Washed well (sping dry was only so so though)
Had a remarkably simple tumble/spin mechanism. One motor, two pulleys, two belts and a spin solenoid Eassy to undestand and repair--couldn't have been more simple than if a six year old had designed it.
The wash pulley was not round, but oval shaped, which gave it a variable rotational (tumble)speed so light fabrics did not ride all the way around the tub, and heavy fabrics would not roll at the bottom. In other words, the theory was that the slow/fast/slow/fast tumble speed would pick up all fabrics, regardless of weight, and drop them in the water from the top of the tub as the tub rotated.
Cool, huh
I orderded a repair manual from WW when I owned it, and they sent me one which had actually been published by Westinghouse before White Consolidated Industries bought the Westinghouse Appliance Division.
If I recall, only the cover of the manual was modified to indicate White-WEstinghouse. Apparently, virtually nothing had been changed in the design since the 1960's, except for the cosmetics.
If you can find one of these machines, I recommend you buy it!!
