1960's Lady Kenmore Electric Stove
Thank you to everyone with your suggestions. There are no numbers on the knob/dial that I need. When one turns the dial, the glass panel above it lights up to show the temperature range. (Some of the dials on my stove have numbers but are a different dial/knob in black as in the photo. They work other parts of the stove not the burners.
I will post photos of the grill tomorrow. At this point, I do not want to attempt to take the knob/dial off in fear that it would break as the other one did. It has a "d" shape opening on the back of the dial to fit on the post it sits on. Once again, thank you so much for your help.
