I have just acquired a very nice old steely with a Gemini Special Tour de France decal on the downtube and a head sticker that reads 'Built by Henri Depierre of Paris'. It is a light frame - a bit over over two kilos with forks in place and has mainly Shimano DuraAce components with a sprinking of Campagnolo bits (levers, hoods, cassette). I'd like to do a decent rebuild on it so need info on its pedigree etc. Anybody heard of Henri DePierre? Any guesses on age? It has a Shimano Crane rear derailleur, and a Rigida front rim with an anonymous hub and a Simplex skewer. Rear wheel is almost certainly not original. Seat post is a mile long with a GoFast logo. Bars and stem not original but I'm told by the previous owner that they were originally Cinelli. Any information or leads welcome.
