the diamond ball is a cool machine too but the later machines with additional features and especially the ones with a carry-over bonus are more fun to play.
Yep; Diamond ball has a cool tulip too but not as fancy as this one by a long shot! This one plays much faster, just tap the start button next to the shooter handle and you are playing the next round.

Also noticed this on the top of the door, doesn’t seem to be a date though.

Even the seller didn’t know the vintage of this one…if only Sansei was as thoughtful and diligent about preserving company history as Fuji-Shoji is with their arrange ball history site pages!
