My aunt had a set like the ones pictured in post 587, but the knows were cranberry red, not blue as I recall. They lasted until the mid 70's when she replaced them with an avocado green set of Kenmore 800's. Growing up my mom bought a set of Hamilton's I guess about '61. Very plain, had a tan control panel. Washer had a black agitator with a red lint filter, made a sort of "hawaii " sound as the water was pushed up and through the agitator. The dryer had the lint drawer in the bottom of the unit and had the germicidal lamp too. They survived until early'73 when they were replaced with the piano key Lady Kenmore's.
