Here is Ed Mitton’s blog with info on the Vincia, and the designer, Len Fehskens. I seem to remember BMS offering the laser cut fins, which I believe were laminated with smaller skins over the core, to provide a fin that had nice tapers on them, with a bit of sanding. (Just up your alley, tbzep, since you love sanding ... )

I’m sorry I never ordered. Might be worth contacting Bill Swaindon to see if he still has the files and might offer to make the fin set.
