Inefficient perforated drum back so good to use on cheaper Pacific Northwest Power.  It would be fun to use that control panel on a modern 29 inch machine.

When Consumer Reports tested dryers in the early 50s, the frog eye electric Kenmore was rated acceptable only if connected to a 50 amp circuit because the one hour timer could not be set for sufficient time to dry loads of heavy fabrics with the 60 minute maximum time setting on the 30 amp circuit. The gas model came equipped with the 37,000 btu burner to make it compatible in drying speed to other gas dryers with lower BTU input burners. Friends of John and Jeff had a Frigidaire Unimatic washer and one of the 37K Kenmore dryers.  They said it took 7 minutes  to dry a load of sheets. If you go through the owner's manuals for Kenmore dryers with the old perforated back drums, the time tables for drying showed a great difference between the gas and electric models. It is a wonder WP/Sears were allowed to market such a poor dryer for so many years; attributable only to the fact that no one was looking. Some very early electric Kenmore dryers even had a fan mounted in front of  the heater stack to boost air flow in hope of improving drying performance so it was something of which WP/Sears were very well aware for a very long time.

The original Maytag dryers were built more on the style of the Hamilton dryers where the air flow pattern was different in volume and direction than in the HOH dryers and in the Hi Speed dryers like GE introduced in the 1957 machines where the airflow was front to back instead of more top to bottom. The older dryers built along the lines of the  Hamilton dryers used two air streams, one of which passed over the heating element and into the drum and the other passed  around the drum to carry away the hot moist air. Coincidentally, the Maytag dryers with the huge perforated drums, the 4400 watt heating elements and the drawer-type lint tray were the only Maytag dryers to earn a check rating from Consumer Reports. They were not fast dryers. They vented through a 3 inch pipe, but they performed well.
