Youngstown was primarily a cabinet manufacturer as in Youngstown kitchens. Next time the picture comes up, I would like for you to count the number of plates, salad plates, saucers and other flat ware in the bottom rack. Then look at the two tiny pieces of cookware and the few glasses and bowls in top rack and figure out how the load is representative of family dishwasher loads. It ain't. Even Frigidaire dealers who did kitchen remodeling were allowed BY FRIGIDAIRE to sell KitchenAid dishwashers because most people thought that they were better. In some ways they were and in some ways they were not. This information comes from a long time, long ago Frigidaire dealer in Ohio that John and I have talked with over the years.
Youngstown joined with Tappan and in later 50s to early 60s, Youngstown ads show Tappan cooktops and ovens. I don't know if Youngstown helped Tappan in the design of their first dishwasher, but I am sure that they would not admit to having two losing designs for dishwashers.
Greg is right and I, too, often thought that the spray tube was pretty good for the top rack, but there needed to be some water source under the bottom rack.
Maytag ads showed their dishwashers up on a low cabinet. They did not open at waist height, but were maybe a foot or more above the floor.
