I'm doing a resto on another Italian bike that was repainted (badly), and there are no clues to what it might be. I posted a similar request myself
here, and the prevailing opinion was that the frame was made by Garlatti. Your bike does appear to have similar lugs, although it's really hard to tell, and doesn't really mean a lot. I see your tops of the seat stays are also bullet-shaped like the Garlatti.
