Kevin -
I am not well informed on Maytags (that will change with continued association here I'm sure) but those machines are not shaded, right? I think the shading ended mid-70s. With Kenmore, I think the first monotone color was in 1976 models I believe.
Oddly, I had one early 1983 Kenmore 70 in Avocado years ago. IIRC it was built in early Feb. of 1983. The last year that seemed to feature a lot of Avocado and Coffee in Kenmores was 1979. The 1980 machines favored Almond, in catalogs anyway, and only a few models seemed to be advertised in the full color spectrum. By the 1981 models, if you wanted brown or green you had one choice in a washer, and two in a dryer (a large cap, and a flat-back standard cap for those who couldn't accomodate the deep dryer).
If the same holds true for Maytag, maybe there were some 1980 and later with the new console in Avocado?
