I bought the bike about a decade ago through a Dutch classified site. The guy selling was aware it was an ex team Panasonic team bike. Back home I disassembled it and rebuilt it. It is pretty much original. The 120mm Dura-Ace 7400 stem isn't. It came with a 130mm Cinelli pantographed XA stem that was a bit too long for me. The PR-6000 catalog bikes did get the DA sem, the team bikes the XA.
What is unique for this team frame are the geometry and details like the extended steerer and seattube, a feature seen more on Jan Legrand designed/built frames.
This was my first PR-6000. Through the years I acquired five: 4 ex team examples (Zhdanov, Talen, Ekimov, Knuvers) and 1 catalog bike. The Knuvers bike and the catalog bike went to the US, the tall John Talen one went to UK (Ed Edwards). I stil have Zhdanov and Ekimov. The catalog bike set you back 6998 gulders in 1991. No cheapy, so not many around.
