cool
yes , it is what you think , most probably … ’ j.b. 's , eat ya heart out !
…I’ve posted shots of the originals … and , done threads on them here , for years !
the fins are , actually , silver tinted …not C.F. haven’t surfed that setup …yet… 
they are replicas of a coupla glassed-on ones , on a board that my nephew butchered , into a twinny kinda thing …
I’m looking forward to seeing your fish take further shape / get glassed / get finned , Tom !
cheers mate !
