Spinout
That's a smart analysis. Given the really wide range of venues that club member machines come from, they could have been cast off from any number of places.
When I first started researching this stuff back in 1969, one of the first things that impressed me was how GE and Whirlpool(another big contract vendor) seemed to have an infinite number of washer models, whereas Maytag, for example, had 4 models, the 906, 806, 606, and 206. It was years later I discovered(were they always there? They weren't in the early brochures)the 106 and the 406. I never saw a 506 or 706. I work in the restaurant business and it's like a low-brow joint with a 4 page menu(that makes fistfulls of cash) vs. a chef-owned establishment with a small bill of fare(that's adored by all the critics and the media, but never makes money on its own).
