Are the ends of the fin base rounded, or square?  Pics are a bit small to get a good “read”.


If round, then it’s a first generation Fins Unlimited. Roughly 1967-68.

Put it on Ebay at $200


the ends are rounded and that you vary much for the info


''...it's a first generation Fins Unlimited. Roughly 1967-68.''


Bang on.
