Haven singlefin

Here's a singlefin I picked up recently, its not quite mint and I don't bother with rating the condition out of ten, I'll just say its damn good and one of the most immaculate survivors of the 70s I've seen. It looks like its been surfed only a handful of times. Made in Bude by Haven surfboards, stringerless and probably from '73/ '74, its got a slim tail and a thick nose so the volume is well forward, mabye a bit too much ! The resin tint is fresh as the day it was born and its got a nice fade on the underside . 6'10 x 20 x 2 3/4 .No shapers name although I have another Haven shaped by Roger Adams. There's not alot about Haven out there and I don't know any more. Anyone ?
