John and I found that oven in a thrift store in Georgia. It cleaned up beautifully and is a champion performer at baking and broiling. Unlike some builtin ovens, the Frigidaires used the same liner as in their 40" ranges' master ovens so it really holds a lot. The broiler is open coil and has a perimeter coil that is used for top heat during bake. When the doors are opened, a heat shield glides out from under the control panel to shield the clock and controls from the heat. The Wilcolator thermostat has an automatic preheat function where, when it is turned all the way to Broil and then back to the desired temperature, both the bake and broil elements are energized until about 50 to 75 degrees below the setting when the broil element is de-energized to prevent overshoot. In my former house, it sat on top of my KDS14 to add stability when the door was opened and the racks were pulled out. We also found the Imperial cooktop, also in stainless steel with the Speed Heat and Heat Minder units. It sat on top of the 1954 Bendix Duomatic and was my first experience cooking on Radiantube units. They were not as scary as they looked, compared to the thinner Calrod units I was used to, but I did know to switch the heat setting from high to simmer at the first sign of boiling and never to put a skillet over high heat.
