My Mom's first dryer, purchased in '62 or '63, was very similar to the one in Paul's picture. However, the control panel was more like the washer the kids are putting sand in, though lower like the dryer shown. Perhaps the dryer above is another model year, a more basic model, or a Canadian variation. These were the last version of the slant-fronts.
Both the washer and dryer got side hinged, inset doors when Westinghouse restyled their machines for 1964. There was evidently a major problem with the door on the washer. The '64 washer we had always leaked around the door, and the door rusted badly. Therefore, by the late 60's they changed the washer door to the style that had been used on the early 60's models. The dryers kept the new style door, however.
