No Filter-Flo until the late Eighties, to my knowledge, ever had an all-white porcelain washbasket, even thought the graphic doesn't really depict a speckled porcelain tub. As most of you already know, there were some all-green and all-blue porcelain tubs and they are rare.
This was a beautifully designed panel, but I imagine it was expensive to manufacture and I wouldn't be surprised if GE incurred a lot of expense replacing a lot of these under warranty because the backsplash was mostly glass and we know what happens when careless sellers, installers and owners try to move washing machines around by the backsplash. I always wondered whether GM copied GE or the other way around.
