That's the dishwasher my parents had before the current 2004 GE Tall Tub. Theirs was a 1987 Potscrubber 900, though I think machines were made with this stying for several years.
We got 17 years of daily use out of ours before the door spring broke. We had to rig the detergent dispenser prior to that, but we never paid a penny on repairs.
You got pics of two of my Mom's long-time kitchen appliances in one day Lawrence, THANKS!
