That is an iconic bike. I can imagine a collector wanting to own it. You might want to consult the folks at First Flight Bicycles in NC, who operate the Museum of Mountain Bike Art & Technology (www.mombat.org) They have a 1991 Ultimate in their collection. Also, a charity auction a-la Jay Leno & Ebay might work well. Bike Forums could be a good platform. As far as text, if you can get some copy from Zap, that would be gold.
Great story.
