Hi ,
Awesome sight !!

I have just picked up an old school Tiga 280 Slalom .
I'm after advice on which fin it requires as it is not the same as my other Tiga 285 LWR which I believe is a conic box.

Anyone who has suitable fins or knows the fin box is greatly
Appreciated

Isn't it just US box.?

I don't know about this particular Board and a picture might Help, but about the time of the 285 Tigas Had a Box that shapewise comes close to a powerbox. I seem to remember they hadcsome nudgevin the Front with which you hooked them in and screwed them tight with a screw from the deck like in a powerbox.
There ist a faint Chance one of them ist Hidden in NY basement. If I find it, I'll post a pic here. Won't bei of practical use, though. Uless you live in Germany, where you could pick it up.
Sorry for terrible mistakes, autocorrect set to Germany on my mobile.

I'm sure this is the rare non-weird Tiga ie just a normal US box
but yeah pic to be safe. You can't put it in the forum but if u upload we can see it on your profile

Something like this? It says Tiga Fin System

I might be able to help out if you can't find anything local or online.
