World's most famous obscure surfboards 3- Blue swallow tail single fin from Sigmund and the Sea Monsters

This is the third in a series of postings where I try to determine the worlds most famous and culturally valuable surfboards, where they are now, examine their history and celebrate their obscurity.
The definition is simple, the surfboard the most people have seen and are aware of.
The next board I'd like to submit for your consideration is the blue swallow tail single fin from the opening credits to Sid and Marty Crofts saturday morning show Sigmund and the Sea Monsters. It looks like a Bing or Hansen.

We need to find out.
a) How many people know of this board?
b) Who shaped it.
c) Where is it now?



Those kids are dressed like surf hipsters from 2011 with their ringer tees, van's surfsiders and cut off shorts.
