Regionality??
I have an excellent memory for vintage appliances and I would always make note of who had what when I was growing up. I swear that I never saw any of these beautiful Whirlpool dishwashers in or around New York City in the Sixties. Saw lots of KitchenAids, Kenmores, fewer GE's, some Hotpoints and some Waste Kings, but never a Whirlpool,especially one with a telephone-dial control.Where were these hiding?
Love the serious dark aquamarine vinyl on the racks.
