I suspect they are full restorations to some level - the seller is a decent sort of fellow to deal with. If you mean are they "re-fakes" like some dealers are doing with MM, I suspect not (he mentions cleaning certain items like ramps), but you would have to check with the seller for certainty and see if you can verify the original components (ie board sets for example).
I concur.
They are clearly not the "re fakes" that have been sold as "originals". It is always a good idea to see the machines "in person" and judge for yourself.
