Whoa....
Wow, interesting. That washer is probably dirtier than most clothes I would be putting in it.
Cool dryer, 1970/1971 60-series model.
The washer is one of two models, either a 1981 entry level 70-series, or a 1982, entry level 70. The '81 had a manual filter, the '82 replaced that with a self cleaner. Both have the DA agitator.
It would be fun to give that washer a good washing of its own!
