Made me scratch my head and chuckle a bit on this when I first saw it. It doesn't look like someone just engraved the name on the core because I've never seen one colored blue like in the photo.
I'm guessing it's a fake, or someone was messing around and poured plug material around an existing ball. Said ball I think would be way oversized. Hmmm... would a dramatically oversized ball carry better? (I doubt the ball returns could handle it though.)
