That was part of Hotpoint's Customline Kitchen where the builtin ovens, cooktops and dishwashers had stainless steel surfaces. We have one of the beautiful double ovens and its cooktop, offered by the owners after they did a remodel and read one of the articles about our collection. The lower second oven in the stack is the half-height oven like they used in their double oven 39" ranges at the time. The refrigerator was always shown recessed into the cabinetry so you did not see the white sides. One ad showed 3 stainless steel cook tops, each with two surface units, mounted in a counter with the backsplash close enough to offer the receptacle for the Calrod french fryer heating element that immersed in the deep well pan.
