Maytag TTs
Are rather rare birds, and those who own them today often tend to "baby" their units, at least those who are interested having such machines around for awhile.
Spare parts are very difficult to find for these units,even more so new old stock. Hoover kept up production of it's twin tub units, in the UK long after Maytag gave up the ghost. Tend to think Hoover USA had much larger distribution network as even today bits or entire caches of NOS parts pop up.
