Based on a catalog, or brochure, I have, your bicycle is probably a Miele Nouvo Corsa. I am including the brochure page for that model and one for the Victory model.
Also, I really like Miele bicycles and I am lucky enough to have one that is pretty rare.
Have a peek at my orange Miele. I call it number 17.
There is something interesting in order of appearance in the brochure. It seems to start with the top model, the Record and move on down to, truly lesser models. Then the information changes to include three or four bikes. Not sure why this is so unless those bikes at the end are of Italian origin.
Hope this is a help.
