Dan, thanks for the closer look at that agitator. The poor resolution and reflections made it appear to have four slots. It makes much more sense now that both were entry level machines for the time period.
I remember shopping for a new washer with my mom in the mid '70s and seeing that the subject standard tub Maytag washer cost about as much as a nearly TOL, much larger capacity full-featured Kenmore. It was no contest, since a giant tub Snorge was being replaced, and she got 25 years out of the Kenmore. A Maytag could have easily lasted longer, (the Kenmore's final issue was minor but I was out of the country at the time) but the closest Maytag would have been a 606 and even at that the tub would have still been smaller, and it would have also broken the bank.
