That thing in the center is just as likely to be something like a rectangular electric skillet where the whole cast aluminum thing plugged out for a good scrubbing. It had the electric element cast into the pan, like an electric skillet. John saved one from a similar stove. Roper was always doing something with that center space. How many of you remember Sears/Roper gas ranges that had a center rotisserie with a rectangular burner on either side, Infra Ray, I think. Consumer's Report stated taht it splattered a lot. Who would have thought that, with a chicken rotissing in the middle of the stovetop? I have never used my Farberware Broiler as a rotisserie. I was told that it does not splatter. Is that true, anyone with experience?
