My mother's first dishwasher!
That looks exactly like the dishwasher my parents bought in I think '71 or '72. It was MOL, the TOL (our neighbors had) had two covered detergent dispensers as there was an additional pre-rinse/wash on the pots & pans cycle, and the top rack of the TOL had additional rails on the sides for double-decking cups. The cycle buttons were pots&pans, regular wash, short wash, sani-wash, rinse&hold, and cancel/drain. I can still hear the clicking of the timer advancing. It was a noisy machine but washed well. I really put it through the paces as I was getting into cooking and baking in my teen years, packing many a "Bob load" into those racks. I think it lasted about 8-10 years. By then it was rusting badly and the timer would get stuck in the second wash phase, washing for hours unless you pressed the rinse&hold button to get the timer to advance.
