Maybe I can fill in some details on these…
Hi everyone,
These are indeed 1973 models that debuted sometime in ‘72. The dryer in fact has a 1972 only door handle.
I don’t remember for certain, but I think the washer was available with and without a bleach dispenser. The 1973 model debuted for the last year of the old numbering system where the model year was the first two digits after the 110. (Sears source code for WP).
Dave is right that these models seemed to be everywhere in the 70s, and there was at least 6 other different plastic panel models from 1972 to 1975 with the hump over the timer. It would seem this was the most common.
There was also a distinct 1975 model that looked almost identical. It was available only with dispensers, and differed from the ‘73 by having a Roto Swirl agitator, and the amusing kicker, the wood grain pattern, which is clearly a vertical grain on the 73s is horizontal on the 75s.
I don’t think the dryers differed at all other than the fake wood, but the 75 washer may have had an OB relay, but the 73 did not.
This looks like a great set.
Have a good week upcoming everyone!
Gordon
