Bianchi ID Help
Don't seem to be generating much interest in this subject. Perhaps the forum is getting tired of such inquiries. I bought this frame and fork with no knowledge of it's history. I came with Shimano 600 crank and Campy(Perhaps Athena?) brakes. I put the 105 group; Sakae post, bars, and stem; Tange Levin headset; and Wolber rims on it. After looking at hundreds of Bianchi images without success, I had almost convinced myself that the year and model really didn't matter. But knowing the designers intent for this bike does matter. So I'm asking for some C&V Forum help.
What I believe I know about the bike:
Frame: Columbus TSX, Made in Italy decal, report corse decal.
Fork: Lugged with blue crest stamped in crown, Stamped Gipiemme on drop out.
Under BB stamped Bianchi with 59 stamped near crank and what looks like half of an H followed by 230 stamped on the other side.
The seatstay weld to the seatpost lug seems rather unusual to me. The rear brake mount is unusual as well. The Bianchi decal on the downtube has a gold border around it.
