That's the exact ryer one of my mom's best friends had sitting next to her 1955 WV65 Unimatic. The pushbutton on the left side next to the little knob is for auto dry.
That's the matching dryer to the washer my mom got for Christmas, 1955. We had it until 1964. She didn't get a dryer until 1963, when the last model of the Westinghouse slant fronts was purchased.
