Yeah, the problem with those is that the main cost will be in the strip down, refurb, cleaning and rebuild. Depends on the condition of the spindles also and many other parts.
Just looking at the exterior cond, I doubt that they are in "ready to run" condition.
You'll need to find a buyer who is prepared to take that work on before use.
You could plonk em on fleabay and take your chances. I may be interested, but as I would not be able to sell them on until they are in perfect cond...I'd be looking very much at a trade price.
