I know it's 80's, probably '84 or earlier. Here are the details I have:

S/N: 1421 3.M

Celeste Green (lovely!)
Columbus frame (the sticker is peeled off so only the "olumbu" shows so that's all I know on the frame)
3ttt handlebars
Strada cranks
Molodo brakes
Campy Nuovo Gran Sport rear derailer
Campy front derailer
Campy shifters on downtube
Mavic rims

Alloro and Made in Italy stickers still mostly there, but way to trashed to save.

It originally had blue tape on the handlebars, but it was stored outside for a number of years and was in pretty bad shape. It's currently torn apart--except for the frozen drive side BB and the frozen seat post; those need to be dealt with soon.

I'm planning to have her cleaned (media-blasted with walnuts, actually), primed, and repainted in Celeste Green, and I am really hoping to find original or replica stickers so any advice on that would be much appreciated as well.

Apply some of the information contained in How Old Is My Bicycle? and you will come pretty close to nailing the vintage of your bicycle. Pay closest attention to Vintage Component Numbers.

Hope this is a help.

Thanks! I'll give it a look and see if I can figure out the year. I've gotten the drive side BB out, but the seat post hasn't budged. I'll be trying liquid Nitrogen on it tomorrow and if that doesn't work, I'll end up hacksawing the seat post out. Since I would really like this to be all stock, it means finding a replacement

Thanks again.

Hi Jim do you have any pics? what color is the remains of the Columbus sticker? did you try a search on here about stuck seatpost? I don't know what methods you have tried already but there are lots of different ones.

I don't have any pics of the bike pre-tear down, but I'll see if I can get an idea of the color of the columbus sticker. It's pretty much black from being outside, but maybe I can clean it off and get some idea of the color of the sticker. The Bianchi crest on the front is the same...pretty much all black. The bike was outside for 3-4 years with no protection, so it's a bit of a mess.

I did search for--and try--all kinds of stuck seat post cures. Sadly, none have worked. I'm planning to try the "cool down the seat post" trick with the liquid nitrogen. I'm really hoping that works, because I'd hate to have to cut the seat post. Of course, I also have to find an original seat, so maybe I can get seat and post as a bundle deal!

Thanks for the help, too!
