Ben,
VERY good info!!! Interesting that the baseplate on the two is different. I just assumed the vanes extended out longer. I wonder why they made the change like that. I can't imagine it making a huge difference.
Looks like my washer and dryer were both made probably sometime around the spring of 1968. Wonder if that was the first year for the 3-speed models?
Thanks so much for the pics and info. Really some great work you've done!
Jon
