My Junior High had a combination of Westinghouse Self Cleaning Ranges and newer Kenmore ranges. I guess they replaced the older Westinghouse's with newer, cheaper machines. I remember the teacher taught off of a GE Pushbutton cooktop, I remember being fascinated by the fact it was push button. They had a portable GE Potscrbubber II dishwasher, I think it was an Encore. BOL. GE Dryer, and a Westinghouse toploader. Pre-WCI, of course.
As for my High School, all original. Nothing had been replaced. All Westinghouse ranges, and a complete Westinghouse washer/dryer set in white. Same model washer as my Junior High. Plus a portable Westinghouse front load dishwasher too. Again, the teacher taught off of a pushbutton GE cooktop. Again, I was fascinated.
Rumor has it, the Westinghouse laundry pair is still there. I have half a mind to call the school board and tell them I am interested in the set and that I would pay them to have it!
