Hello Mike. unfortunatly we may never know just what this Bianchi was. there is just too much missing tubing decal, the "Bianchi" decals, and of course the components. Bianchi often used the same frame for different models so even if frame was in almost pristine condition, without the parts there is no way to know.
it does look alot like a frame I just picked up and near as I can tell it is an '83ish Nouvo Record frame. I came to this conclusion by comparing the frame to the catalogs using, tubing type decal and location, type of Bianchi decal, BB cable quides, placement of RD housing stop and nonrecessed brake bridge.
