Thanks Ben. It's mostly a curiosity, but I know others here have pointed to them for all kinds of interesting tidbits about mid-year changes or updates to procedures. Most other Maytag information is more easily available, one way or another, such as the Ephemera here or via auctions... but aside from the occasional sale of a few years here or there, the long-term periodic service information from Maytag seems to be quite difficult to get copies of.
It's of interest to me, as I know they contained some of the updates and service information that came long after the service manuals were published.
