Find of the day: Gitane bike with Campy parts

Nice. 1974 - 1977 Gitane. It's not a Tour de France or Super Corsa as they were Reynolds 531, but perhaps a Criterium or Super Olympic or something like that. The vintage is that of Lucien Van Impe when he won the Tour, of Bernard Hinault when he first turned pro. Old gitane catalogues here: http://www.gitaneusa.com/catalogues01.asp

I was wrong, it actually is 531 tubing! It looked like a 0 to me, but I online how the sign looks and it's definitely 531.

The SUper Olympic from 1975 looks pretty correct, at least the decals, colour and the groupset match.
