Anyone know who made this fin, found it.

Legendary fin maker from Lancelin 20yrs ago...... on the tip of my tongue... nup lost it

Handcrafted by Andrew in Lancelin WA. Unfortunately he's no longer with us:

I've still got a number of his slalom fins from way back and maybe a weedy or two, with my slalom 29 reboxed from Tuttle to PB by Andrew close to being one of the best performing fins I've ever owned, just behind my FF22!
