Judging by the features listed in the ad, this machine uses 50% less hot water and total water than other washers. Does that mean that this is still a solid tub machine? The other feature which states that the machine has no gears sounds like the old Kelvinator drive for the Xcentric agitation. The final clue to this being the old design is the window in the lid. This ad features late 60s colors. I don't know when Kelvinator became another generic White-Westinghouse machine, but I guess it was later than I thought.
