Good eye, Tom, I wondered what that glass was.
I have a Westinghouse parts book with this dishwasher/sink in it, couldn't believe it when I first came across it. I have seen pictures of a kitchen in the old power company building that had a Westinghouse kitchen set up as a classroom/lecture room, dishwasher and all. They probably did cooking classes and 'living better electrically' seminars on how to get the most out of your new electric service -- and buy appliances through the utility.
It's a very beautiful kitchen, from the handles to the original appliances. I love the big windows letting light in. A bit hopeful on the price, but you never know. Pulling site-built wood cabinets and refitting them in a new space wouldn't be easy or fun.
Is there any more of the story of how the kitchen came be unused and preserved?
