Sorry to bump this back to life but.....
This thread has been a fantastic help to my son and I.
We were both over the moon to have finally found a real Italian road bike and a Bianchi to boot.
Turns out it's an 87 Super Legerra, all original with the same unusual script.
The original Super Legerra decal had come off but you could still see the strange script.
It wasn't until I found this thread that I was able to completely decifer the model.
Originally it was a Birthday gift to myself but as my son and I have been working on the bike
my son has fallen quite in love. Funniest thing was when we got home he said to his Mom..
"Mom, I'm in Love and her name is Bianchi!" LOL!
I'm not sure what the outcome of this is but it for sure mean's I'll be looking for another
beautiful Bianchi.
Thanks to all for the insight

P.s. Anyone know if there might be a source for the script Super Legerra?
