Bianchi - Celeste early 1990s

I bought a Bianchi celeste-colored bike sometime in the early 90's. It's been modified somewhat from the original components. Small frame, 19.5 inches-49.5cm. I want to sell it and am trying to determine what model it is. Have looked at many photos of vintage celeste Bianchis, but cannot find any with red in the decal. Mine seems unique. Logo is bright blue, with a red graphic block at the beginning/end of logo depending on which side viewing it at, and a very thin red line through the logo. I want to sell this bike and thought it would help for someone to know what model it is. Small frame - 19.5 inches/49/5cm. Made in Italy, rather thin Columbus tubing.

I cannot post photos until my 10th posting. Oh well.
