That 1958 Whirlpool range was tested by CU. They checked for the safety of the controls of all of the ranges in the report by leaving a rear element on high while unattended and without a pan. The WP control panel melted down to the point where some of the slider controls were unusable.
The Presteline range, if you will note the small print, was made by the presesed steel car company. This was the range which featured the 6 qt Presto deep well pressure cooker. Mirro made the deep well pressure cooker for Frigidaire ranges and Ekco make the deep well pressure cooker for GE ranges.
In the 60s, Monarch electric range ads touted their convection ovens which had a fan in the bottom of the oven. At the time, I had never heard of Monarch ranges. In the 1940s, they had interesting features, like not only a deep well, but a shallow well with heat not only on the bottom, but also around the sloped sides. It was usually shown with an enameled Windsor-shaped saucepan which, I guess, came with the stove. The surface oven was like a roaster oven in the cooktop, again with the heat coming from the bottom and the sides for small baking jobs and other roaster oven meals. When the surface oven was not being used, there was a flat cover for it to give a work area.
