1980s Hawaiian Style quad

Here's a board I picked up from the local car boot this morning. Its an early 80s quad made by Hawaiian Style. I can't find anything about the label but its a British made board and I'm guessing it was made in Newquay or possibly South Wales. It still has the original shop sticker saying supplied by the Newquay Surfing Centre in fore st.. Artwork is by Chris Gadd and glassing by 'the rattler' , no shapers name. I 'm hoping someone out there might know something about Hawaiian style boards ?
Its a nice 80s shape with quad fins, four channels and two small stingers in the tail, dimensions are 6'4 x 20 1/2 x 2 1/2. I guess the name was cashing in on the craze for all things American at the time and the board has US clark foam 'blue light' and 100 % American resin.
