The 1949 Bianchi Folgore on Carsten's site has some interesting details:
Celeste-colored thin (Gaslo?) handlebar tape.
Two-piece rear fender.
Sharp angle, not rounded, on the lower leading edge of the dropouts.
1-piece Y-shaped fender mounting brackets.
Are there slotted cutouts on the right crank arm, near the bolt circle?
Red pinstriping around headlugs, but only against the beige-looking headtube, and no blue details on the chainstay dimples.
Rear fender bracket mounted behind the acorn nut on the rear brake!
Earlier-style notched headlugs, without the continuous curve of later models.
