There is a new website dedicated to classic Campagnolo parts and related memorabilia. It even outdoes the venerable Satorumas site, so do take a look. Hiroshi Ichikawa is also an extremely likable fellow who also openly shares the information he has.
At present, he has only been able to prepare a text in Japanese, but it would be truly great if a translation into English were possible. It should also be mentioned that a photo of John Pergolizzi's Cinelli appears in the headset section.
Unlike the well-known Kauzo and other Japanese collectors, Hiroshi does not appear to rely on Ebay to find his many incredible items. As an avid cyclist and working as a 'Salaryman' he is also not a deep-pocketed collector without any apparent immediate ties to riding. He has toured extensively and raced.
