Mid 80s SQ Stacked Washer & Dryer
This is indeed essentially the same washer mechanism as what SQ used in their unusual tilt-out stack machine. The only real difference in the washer was that the washer in the stack used an electric drain pump so the stack machine did a much better job of getting grit and sand out of loads of clothing because as the machine was agitating the grit could just settle into the outer tub. Then when the washer goes to drain only the drain pump comes on at first till the machine is over 1/2 empty [ partial neutral drain ] and then it starts spinning to help flush dirt out of the bottom of the outer tub.
