One of the first washer tops i picked up off "the curb" years ago (1980). It was just the top and control panel from a few blocks away from my home.
Those buttons are incredibly brittle and broken easily. I'm surprised, after all these years, that yours is in as good of shape as that.
I also picked up a mid 70s Kenmore dishwasher door on that same street. I suppose the removed the doors and tops because of all the fear that was going on back then for kids crawling into machines and getting stuck inside.
