Re Stepped top
The Terrace top, as WH called it, was a good idea, well sort of, the idea was the pot handles on the back units wouldnt interfere with the pots and pans on the front units, also things on the lower level were easier to see when stirring, Two of my Mothers cousins had them as well as one Aunt, they all said the same thing, for normal cooking it was great, but try to get a pressure canner centered on the big unit......that was not so good!
