Bob,
GE's TOL ovens used 'Dinner Dial' controls, which were just lightly different from the conventional setup. I had them on my 1961 40" range and they were neat. The left dial still functioned as an "Oven Set" knob and the right was the "Oven Temp" control. Here's the description of their operation from a 1960 Owner's Manual:
"OVEN SET has settings for BAKE, TIME BAKE, ROTISSERIE, BROIL and OFF. The knob when turned switches the proper unit(s) on for the desired operation. The position at which the oven is set will show in the window between the OVEN SET and OVEN TEMPERATURE knobs. At all positions other than OFF, a light comes on in the window and stays on until OVEN SET is at OFF position. In addition, an oven signal light below the control goes off when the oven is preheated to the set temperature, and then goes on and off with oven unit, during cooking.
"OVEN TEMPERATURE knob is used to set the desired heat for the food to be cooked. When the knob is turned in either direction, it will move a red indicator behind the temperature scale."
These dials were fun to work with, but had to explain without standing right in front of them. What these instructions fail to explain is that when the 'set' knob is rotated to OFF the temperature scale in the window disappears; it rotates in conjunction with how the 'set' knob rotates.
