If there is a will, there is a way
Hi Geoff, like any 40+ year old Automatic, its EXTREMELY rare to find that it works properly, obviously this Maytag doesn't, but you wont know exactly what is wrong until you give it a thorough examination. Then it’s going to have to be taken apart and restored. The rust on the wash basket might just be surface rust and which will come off with Bon-Ami and lots of elbow grease.
If water was in the wash basket, then it probably won’t spin, but that could be from a number of reasons, such as the timer, electrical wiring, spin solenoid, brake assembly or spin torque spring.
If really want the machine, go for it, worse comes to worse you can use it for parts when and if you find another AMP. Even though parts are very rare, if there is a will there always will be a way.
BTW, its not just you, what you experienced with the recyclers being rude and not willing to listen seems to be a common experience throughout the entire world. I found the only way get their attention is to talk to them in their language and offer them lots of money. Even with that, of all the ones I spoke to, only a couple had ever called. One actually turned out to be a gold mine, but he says unlike 10 years ago, now its getting really rare that he sees any washers from the 50's anymore. Of the 1000 or so units he sees a week, only one 1 in nearly 75,000 to 100,000 units will be that old. Its the same at the estate sales, Vintage Dryers, Ranges and Refrigerators are plentiful, but the washers and dishwashers are nearly gone.
