Simpson Surface Cleaners

I have three (3) Simpson surface cleaners - none of which work for various reasons - I bought a new surface cleaner because I don’t have the time nor the skill to “work” on the Simpsons.
Is anyone out there interested in these things for parts? I would like to sell all three of them and I would think if someone wants to put the time in to them you could have one good surface cleaner.
If you’re interested email me.
