Those are very unique cycle buttons. I've nevfer seen a kenmore like this at all. It kind of reminds me of a lower-end version of the 220V LK Rotorack kevin got with the Bendix pair. I base that comment on the door handle plus the shallow blue rotorack.
This is the exact model KM DW we got in the fall of 1966 when my parents had Sears remodel our kitchen. The interior is identical to the 240 volt LKM DW that Kevin got a few months ago witch is way I decided to buy the machine from him, it just brought back so many memories. On this model the pink button gave you a 145F second wash and last rinse this machine is 120 volt with a 1000 watt heater Kevin's LKM has a 2800 watt element @ 230 volts. The LKM DW will not be put into ever day use but will be hooked up at the museum where people can see it work and even run dirty dishes through it.
