We had this dishwasher, I think it's a '72. Gold racks. Ours was white, what a fun dishwasher to have as a kid. FYI, saran wrap is not a lasting substitute for a door.
This was the very last rendition of the Roto-Racks because it also included the hot dry/cool dry switch that's to the right of the timer dial. This was the exacyt model (but not the energy saver dry switch) we had in our house in Houston. Gansky1 found one of these several years ago. It has the water temperature display lights the cycle names light up over the pushbuttons and a light shines down on them and a little idiot red light abov e the timer knob. This was also the model right below the LK.
