My Papaw had a Westinghouse for a short time between the times he had the two Filter-Flo's. It was either MOL or BOL, but it seemed to have plenty of features for what was needed. It had a straight-vane agitator, but was complete with the counter-clockwise tub indexing and the lint filter tray.
I actually had a question about the brochure in the POD where it states "The wash tub indexes in one direction while the agitator agitates and indexes in the opposite." I know that the tub indexes, but I always thought the agitator, while oscillating, still turns along with the tub, as to prevent wrapping and twisting. For example, if you could somehow mount a camera to the tub, pointed towards the agitator, the agitator would move back and forth to the same points as though the tub wasn't actually moving. I know that's how it is with the Frigidaire tub-indexers, and I assume they took that design through some kind of company buyout.
