Now if I could find a NOS washing machine that had never bee
I saw one of these in person in 1970 at Gimbels department store on Herald Square. Where Macy's carried GE, Westinghouse, Norge, Maytag and Hoover, Gimbels sold Hotpoint, Whirlpool, Frigidaire and Maytag. Gimbel's also had the Whirlpool "Woodies" that year too. I remember opening the lid to the Duo-Load and being surprised at what looked like a row of plastic fins surrounding the main tub which you couldn't see because the Duo-Load tub and its cover were so large they took up the whole circumference of the opening.
I think this information was sent to me by Tom Turbomatic or by John Combo 52 or by Gansky (sorry, all you white people look alike to me): Basically, most of the trick for the Duo-Load is in the mini-basket and its lid, which is a carefully and intricately engineered <span style="text-decoration: underline;">cover</span>, NOT an agitator-mounted lint filter pan which is what it looks like. When using both tubs, the solid tub-style "metered fill" sends water directly onto the cover of the little tub which sits on the agitator. The water is directed through little channels and chambers into the mini-tub. When the mini-tub fills to capacity, small plastic floats in the cover seal off the inlets and then the same water flow is redirected via other small channels in the middle of the cover down alongside the agitator into the big tub. At the same time, the meter is preset (like a timed-fill machine) to sense that the small tub has filled and then changes the temperature of the fill water to whatever is chosen for the large tub. When that preset level is reached, agitation starts and both tubs go on their merry way with their separate temperatures. There is a gasket in the small tub that prevents any water from that tub from spilling into the main tub during washing. When the spin cycle starts, the throw water from the small tub is directed up and out via channels in the side walls of the plastic basket and is directed via those plastic fins on the side of the main tub I told you about, so the waters from both tubs never meet until they reach the outer cabinet where they spill down to the drain pump. This machine also had a fountain-filter and fabric softener dispenser(which I've never seen) both which could be used when using the main tub only.
It's a wonderful design and I'd love to find one of these but it does look like these weren't built to last. Consumer Reports was especially nasty to this model. It received the lowest rating for 1969's extensive washing machines report and they even rated a lower-caste Hotpoint model (the one Pete has pictured above with the white doughnut bleach dispenser) as superior to its TOL sibling. One of CU's big complaints was that the agitator was especially over-engineered with an internal bleach dispenser and lint fountain filter (which didn't work when using both tubs, BTW) and difficult to take apart to clean out sand. That was also the year that CU complained that the top-rated 'Tags had backsplash trims that were "inconvenient to clean". Oy.
It's also interesting to note that during the tenure of this model, from 1968 to 1971 their companion Hotpoint dryer was changed from a 31" wide real Taylor Avenue Hotpoint machine to a 27" wide GE appliance park model dressed up to look like a Silhouette. The models pictured below were the first 1968 iteration.
