If you stand in front of that lighted control panel for any length of time, you would not need a light box for Seasonal Affective Disorder. Then behind the rest of the controls, you have about a Christmas tree light string's worth of C-7 bulbs to inform you of what's happening. What a shame it's only a single oven with a warming drawer
In the picture on the lower right in the link, the thing that looks like some sort of small antenna is the popcorn stirer. The rounded base it is sitting on snaps into the three projections under the cover of the deep well Thermizer, which lets the two big loops rest on the bottom of the kettle. Once you add the corn and oil, you simply turn the cover to stir the popping corn. It's just like commercial poppers, except not motor driven and much easier than trying to shake the stove or grabbing the Thermizer and shaking it up and down in the well.
The little round rack with feet and handles could be lowered into the Thermizer well and used for baking potatoes and other small items. The feet sat on the three legged burner support to keep it above the element.
There was a spring-loaded thermostat in the side of the Thermizer well that pressed against the side of the kettle. When the kettle was used for deep fat frying, you started the fat heating on HIGH. When the fat reached the proper frying temperature, you were alerted by a signal light to switch the heat to MEDIUM HIGH, which only heated one of the two elements in the Radiantube unit giving 50% heat. The thermostat then cycled that heating element off and on to maintain the temperature of the fat for frying. You don't really want to think about all of the splatters and fat being carried by the steam up across the control panel during that operation. This stove saw pretty light use and good maintenance.
