The S.74 was a large airliner seating a maximum of 27 passengers. The photo seems to have been taken on 27 March 1935 when the prototype, I-URBE, was flown to Rome - Urbe airport. The three examples built served on the Rome - Marseille - Lyon - Paris route until 1938. They were then sent to Tobruk in Libya and fully militarised in 1940. All three were lost during the war.
