Cool!, thanks, well hopefully if Ace gets in contact, I could figure out if Seebold had anything to do with this board. I got hold of the ad Sammy mentioned, and it didn't mention Seebold.
Someone at some point went through a heck of alot of trouble to re-fit a big Rainbow fin with a ton of resin and make it fit into the WAVESET box on my board. They did a pretty nice job making it fit snug, some feat considering the taper of the box, and angled sides. Too bad they stuck in a leash plug though!
