I have one like that, in electric. It is pretty basic, but, a little more uprgaded in that it has a stainless steel control panel insert and full hamper door and in the lint filter has a control for end of cycle alarm volume, with soft heat timed or auto dry, or air fluff, and a light in the tub.
It is a great dryer,and way ahead of it's time for capacity and gentle but fast drying. I figure 1972 for mine. Just put in a new motor and blower wheel.
I wish they did make a washer to match, the low slant control panel is cool! Can you imagine a matching set?
