I have recently purchased a vintage Bianchi, Celeste, columbus tubing, made in Italy sticker. I was told it was a 1984 but now I'm not so sure. Everything on the bike is Compagnalo even the brake pads, Mavic module e rims, wobbler original tires I believe. I can only find one number on the frame that's remotely close to a serial # but it seems wrong. The serial I can find on the bottom bracket is A.935 which seems short. Also it's all the way on the bottom instead of where they usually are. I have seen many similar bikes to mine but none exact and also the fork seems different then most frames that look similar. Instead of having a more boxy, angular fork with a big "B" on both sides I have a slightly more rounded (still lugged) with a small side triangle and the whole word "Bianchi" in a 3/4 circle on both sides. I will post pics if anyone can help me later on. If anyone can help I'd greatly appreciate it, I definitely overpaid for this bike I think lol.
