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.

HJad a 1973 one of these but was the TOL got it at Wards as a scratch and dent but these were convertable and was cheaper than the builtin.  We moved in 1977 and took it with us to the bew house and put the builders GE in the old house.  Was loud but washed great.  Was one of the best DW's we have had over the years.
