The reputable restorer is HSA pinball in the US
The seller is also a member on this forum and it's not me
If that is the case, it would increase the chances of selling the playfields if it was mentioned. If I had a requirement for this playfield and I knew HSA had restored it, I would DEFINITELY pay more than if the restorer's name was NOT mentioned. If the seller is reading this thread - add the name - but at the price that the playfields are currently fetching - it might not be necessary.
I know that every time I see an unnamed endorsement on a pinball related eBay auction, I'm always skeptical. But it is great that this particular one has been verified.
