Hello welcome to the forums. this is the correct place to post this. nice looking Bianchi, too bad you can't move to Stamford Ct or Elmira where you can enjoy it.
I have a few questions. what is the tubing sticker on the seat tube say? also what brand are the dropouts and forkends? rims and hubs?
judging by the decals this looks like an '84/85ish Bianchi but most of the parts have been changed. I think all that is original is the shifters, derailleurs and possibly the bubs. the cranks are late '80 early '90s Chorus or later Athena. the daul pivot 105 brakes first came along in '92 I believe and that seat pin does not look original.
I think depending on the frame material and the dropouts maybe $300 is a fair price for this depending what model the frame is.
