As BG mentioned, it has the paint scheme of European Bianchis. I've personally never seen a bianchi fork crown with the emblem, but without the word "Bianchi" written underneath. As well, the logo on the seat tube is new to me. To be honest, I'm suspecting:
1. the fork isn't original to the frame
2. a possible repaint? The BB says 8.M, which by my understanding, means the bike was manufactured in 1988. The seller describes it as a late 90s bike. Anyways - I don't know a lot about european bianchis and how they appear, but I think the question is worth asking.
Pic is a European Specialissima from around that era as reference.
