The badge on the side seemed familiar and I hazarded a guess that it was a Farina badge. With that and with the "stabilmente" you indicated I cracked it, it's a 1948 Fiat 1100 coachbuilt bodywork by Stabilimenti Farina. Stabilimenti Farina folded in 1953, and had the distinction of being the original employer of Pietro Frua, Giovanni Michelloti, and Battista Farina (brother to the founder of the company, Giovanni).
