Hey there RCD, you are quite the appliance renaissance man of late, GOOD FOR YOU (and good for the machines too)!!
This is another odd-duck dryer. For reasons I don't have a plausible explanation for, Sears offered a number of different "one-off" models in the 1970-1974 time frame that were at least partially inspired during another time - the 1960s.
There were at least three dryer models, and a handful of washers that used versions of 1962 to 1968 Kenmore panels, coupled in many cases with 1970s knobs, as in this case. The panel frame design on your dryer goes back to 1966 I believe with the model 70. Some other models during the same early 70s period used panels right out of 1962, even with the little indented boxes on the left side and the raised 'Kenmore' bar on the lower left. The phrase 'Heavy Duty' was added that had not been there in the 60s.
I have a 1973 Kenmore dryer that almost perfectly matches a 1965 Kenmore 400 washer, even down to the timer knob. Yes, they used metal timer knobs in 1973 on that model. I don't know if this was to clear out old blank stock panels and other raw materials, or if someone was really in a retro-nostalgic mood in the Kenmore design offices, but I never saw this repeated after 1973. It seemed like in many cases the models were not paired, meaning the dryer was a lone model, or the washer was, etc.
NICE find Andy.
