Regarding Bianchi fork crowns in the 80s. "The Fabulous World of Cycling,
1983 Season" (p189) shows Tommi Primm (Bianchi Piaggio), winner of Paris -
Brussels that year. His fork has the semi-sloping crown, it looks like a blue
"B" in the top of the crown, It's chromed around the edges and the top face
is Celeste. I looked in the 1984 season book, and there are no detail
pictures of any Celeste bikes.
