The Chilli 2008 was the last Chilli before its successor, the Rodeo took over. In all likeliness, it's one of the prototypes in between, preparing fpr the Rodeo 98 or 107, the latter being my guess as it had 67 cm of width.
Another link in German:
www.surf-magazin.de/boards/freestyle/f2-rodeo-air-98Patrik Diethelm, Karin Jaggi and probably Daniel Aeberli as well usually spend their winters in WA for training and testing and often sell much of their gear before going back to Europe.
Probably designed and shaped by Daniel Aeberli of Choco Fins (as on the sticker on the nose of the board) who is now with Patrik boards as well. That's where it probably comes from and if so, the retail store would have been in Geraldton perth or around.
If I really wanted to find out more, I would send a very friendly email with the photo to Daniel Aeberli via Choco Fins or Patrik.
Let us know!
Cheers,
Sven
