The Catskills !
So much history there.
Good for you for saving it. It's going to take some work to clean up, but it looks salvageable.
The underside of the lid, and the control panel look incredibly intact and unused. The underside of lid, at least in the pic, looks so shiny. That's not something one would expect from a used washer with a waterfall lint filter. One would expect to see splashing or soap scum residue. The body doesn't look scratched, dented, or bent and misshaped(as can easily happen with belt-drives) as though it's been moved several times.
I'm wondering if this is another lightly used machines that was simply set aside and forgot because the owner didn't know HOW to use it. If that's the case, it could be under all that mouse poo and dust, it will shine like the underside of that lid.
Here's hoping.
Just remember clean carefully and don't use anything that could scratch, or chemicals that can desolve graphics and paint, at least not the first wash. I'd put that machine outside, on a hard surface and get a hose and gently hose it down and out with cold or warm water. Do the dirt in layers. If you can remove the control panel with the graphics and wash that separate, that may help to preserve it.
I'm sure a agitator cap and lint filter will turn up. That's the least of your concerns now.
Good luck. I hope to see updated pics.
