Great Find!
Our neighbor had this dryer. There was an upgraded model with two levers, one for start and one for high and low heat. There were two washers, one with one lever for hot or warm water and one with two, with the second lever for the water saver. This dryer had the heating element in a flattish rectangular duct behind the drum which had a stationary back with a rectangular inlet grill. This meant that a felt seal was needed around the stationary back. In the mid 60s, these control panels were replaced by a full width plastic panel that was gray and white, but with the same large white timer dial. The washer with the solid plastic control panel belonged to a friend. It was a V-12 design, but without the FilterFlo feature. Bruce, did your washers have FilterFlo?
There is a picture taken in Gloria Swanson's kitchen in her New York City maisonette and the washer with this pod-type control panel is shown behind her.
