I don't know? They don't look like they are necessarily "restored" to me. Maybe the gun game but the pinball machine doesn't look like it. They all look like they might just be originals in very good shape. What does the seller claim they are?

Yeah you can tell there has been some polishing done to the pitch & bat trim. The gun game looks original but it may have some fresher varnish applied at some time. It's hard to tell but the pinball machine looks unmolested.

They are all nice-looking. I'd allow them into my gameroom!
