That fin is a first generation Fins Unlimited. The box system and fin were only made in 1967 and 1968. It is huge. They do make reproductions of these fins but this one is an original survivor.
Yeah, both of those cues are rad. Esp. the Con CC minipin. Looks fairly virgin too. Be afraid to ride it with that lexan fin though, don't they get really brittle after 40 yrs. or so? Love to see survivors.
I was gonna say, that fin looks like it would shatter if the sandbar looked at it wrong. Can't be too many of those still hanging in there.
