First it mentions how the perforations in the Spiral Dasher allow water to pass through thus drawing fabrics into it. I remember how the water movement in the Bendix Economat with basically a perforated Maytag Gyrator was so much more vigorous than in a Maytag automatic, partly because of the wider flexible tub and possibly partly because of the perforated agitator.

The second thing I noticed was the address which reads:

APEX Electrical Manufacturing Division

White Sewing Machine Corporation

This was the beginning of  White Consolidated Industries.

That agitator looks like it would cause a lot of wear on the mechanical parts of the machine.
