VERY Cool machines Brian!
That's a shame about the rust in the dryer, it otherwise looks very lightly used. Note the lack of lint underneath. Those door hinges ought to be easy to find, maybe even new still as they were used into the 1990s on a few KM and WP models.
I have a slightly similar situation with drum rust in that I have a 1962 Kenmore 70 dryer that has never been used. Sitting in a Connecticut basement for nearly 50 years allowed some humidity to collect inside the drum, and cause some light surface rust spots in one part of it. My thought was to try to buff it off with some automotive buffing compound, with the goal being to to save the original drum finish otherwise, but I don't have nearly the amount of work you do in your drum Brian. Please let us know what you decide and how it works!
As to the washer, I have a feeling that the dirt and dried up whatever on the bottom of the basket will wipe off, or come off fairly easily with a wrag or a yellow and green scrubby kitchen sponge.
That's a cool washer in that it has, among other things, the powder blue agitator, which I believe was the first splined, plastic Super Surgilator after the black bakelite Surgilator. It wasn't very long (few years?) and these were switched to white.
