This is a beautiful set that was very well taken care of. At first glance, I wasn't entirely sure the dryer was an exact match, as the timer dial is slightly different, but the catalog page clearly shows that it is.
I have seen the washer in someone's house long ago, but not the dryer. There is a water level switch at the far left lower corner of the panel, everything else is controlled through the timer dial. A small red rectangular light above the timer glows during the wash and rinse agitation periods to show that the lint filter is working. It's the kind with the marbles in it that makes that cool sound.
One interesting thing about this washer is the lid is still kind of the way it is supposed to be when open; she must have handled it with care, which is nice to see. On many Sears machines, particularly the older ones with the heavy porcelain lids, the "lean" when the lid is in the open position becomes very exaggerated much further to the left than it's supposed to be. I'm not sure why they weren't designed to lie all the way flat like some of the other brands.
I always loved the dryers with the brushed aluminum lid for the lint filter. Am I right in guessing that this would be one of the earlier models that employed the full width door? Since there is no temperature dial, I'm guessing the drying cycle is timed, and that small part on the bottom is for no heat tumbling. I'm guessing they must have used a temperature they judged safe for most fabrics for the timed heat cycle.
