I agree with JKB on this one.It's probably a stock board because someone (rightfully) rejected it when they came in to pick up their custom order.
I'd also like to add that some of the those boards are custom orders from Japan and they do change some of the fin positioning for the Japan orders... but i cant imagine them asking for that? I doubt Tomo would have approved that type of fin positing for that model.
@Jamby if it's your dims, maybe ask for a big discount and then pay to have new fin boxes installed. That board goes better as a thruster anyways. lol.
