This looks like a very early "Convertible-portable". Our downstairs neighbors had the built-in version of this BOL. My Mother always groused that this was the dishwasher they should have installed. She hated buttons and bells and whistles.
Ken these in the jpg are later models we had the portable with 2 buttons. It was a good machine but loud. The joke of it was it said whisper quiet on the front panel.

Man. These always show up so far away!! There was an early yellow hotpoint someplace over there too. My whole kitchen is early hotpoint. If anyone has one of these near western Washington or is moving from Cleveland let me know!
