Webmaster Robert commented on the Easy/Westinghouse connection in an old thread, but don't have the time to find it. Here's what I remember:
1) This was the first Westinghouse top-loader on offer. It was, indeed, made by Easy, and I believe the year was 1963.
2) The Easy-made washer appeared for only one year, after which Westinghouse used their own design.
3) Don't know if there was a matching dryer for the Easy-made model. Have never seen one. I would think one existed, as Westinghouse was very style-conscious, and I can't imagine they'd try to pair their spiffy new top-loader with a slant-front dryer. And if one existed, I don't know if was also contracted through Easy.
