The NX was a lot lower in price, wasn't it? I think, as you say, Partscounterman, they used those machines to convince the buyer to upgrade to a different model. They made them look ... well ... sort of like a canner, don't you think?
I couldn't believe it when I saw the pictures of Robert's demo "J" ... complete with a Pyrex shaftless agitator! Wow!! One of the Maytag News I have from the early 1950's has a picture of a glass tubbed "J" with the shaftless agitator and they were doing a demo where you braided 3 towels together and then put them in the washer. The towels would become untangled in just a couple of minutes!! If I don't load my queen-sized sheets properly in any one of my machines, I pull them out all tangled up; not sure how it would untangle braided towels?? Maybe it has something to do with the shaftless agitator?
The "magic" to the gyratator was that it created water currents that kept the clothes moving towards the center of the tub and not the agitator dragging the clothes through the water.
Wasn't the original gyratator a shaftless one? What was the purpose of putting on a shaft? Does anyone know?
