This classic retro all-in-one cooker in shiny chrome and black phenolic is the Cook-N-Fryer model FF-531 by Westinghouse Electric. It's large and very sturdy, measuring 8 inches high to the rim by 8-3/8" diameter, not including the wedge side handles. Capacity is 5 quarts with room for stirring and simmering.
It's super clean for a 60 year old kitchen appliance and works well. The temperature dial ranges from 150 to 450 degrees. It's lighted and has a transparent Bakelite color wheel around the edge - red, yellow and green. Various dishes and foods are listed on the label with cooking temperatures. The 5-plus foot rubber cord and plug are in excellent condition with no damage, splits, or wear. If you want to use it as a deep fryer you may need a metal basket, or just do what I do and forget the messy dripping basket and use a big slotted metal utensil.
