Rob -
I have a question for you. Do you think it possible that your grandmother's washer received at some point a replacement timer? If her washer had the exact same cycle layout as Moppy, then a second-generation replacement timer could be the reason it didn't have spray rinses.
The timer in Moppy and others like it was used for 12 years. That is a VERY long time - many timers in 1960s Kenmores were used only one season or even just on one model or two. This timer began use in 1974 in a couple machines, and lasted until the end of the belt-drives in 1986. During the late 70s and early 80s, it very possibly was the most common timer in existence.
There were three generations of this timer, as minor changes were made to them mechanically, etc. The second generation, for reasons unknown to me, had the lead or terminal moved that provides power for spray rinses. To make sprays work in a first generation machine, a jumper wire needed to be installed in the wiring harness and quick connect block. This is not a big deal, but it is a little time consuming and for those who don't like splicing wires, it may be a bit tedious. I am a fuss-budget in doing repairs, but for guys where time is money and they think someone won't notice or care, I am sure that some of these splices weren't done.
The third generation timer supercedes the other two generations and is a one-for-one plug and play timer. I love Whirlpool for that reason, meaning they make changes to production parts like everyone does, but they make changes happen in such a way that they still support existing product with common parts - at least when possible. This third generation timer had three active spray terminals, which accomodates the two older generations, so no jumpers were required. This was noted with a paper flier with each new timer. Kinda cool to me.
One of their other popular timers, which had a Pre-Soak in the cycle mix, still requires a jumper wire to this day.
Also Rob, the Hot/Warm temp selection was pretty common for Kenmore in the 70s on machines that didn't have five temp options, or the lesser switches which accomodated HOT / WARM / COLD (those machines gave the same temp for rinse as wash except on hot which had a warm rinse).
In 1979 when the 'energy saver' notations appeared on Kenmores, the three temp combination machines got all cold rinses and this was never changed back.
