Wow, now that's a very cool dryer, hopefully someone will grab this one. If only it had the matching washer, although one thing I found interesting was the familiar GE/Hotpoint drain hose sticking out of the picture. Despite how the design changed, at least they were still brand-conscious!
I saw this type of Hotpoint dryer in the 1961 (I believe) brochure that's posted on the site. Instead of a reservoir a la Filtrator, this particular machine actually connected to a water and drain line, similar to the combinations? I'm curious to know more...
