Sorry for resurrecting such an old thread, however I believe I just found an image of the absolute very first General Electric dishwasher from the early 1930's after GE acquired the Walker Dishwasher Company. Just wanted to put it here for reference as this is the thread it should go in...
It is so beautiful, like something you would do, I thought maybe you had excavated out to the side. There was a rock group called the Walker Brothers and every time I heard their name, I used to think of the Walker Dishwasher people.
