Scanned from an original Mario Circovich (1877-1931) photograph of an Italian CNT CANT 13 single engine seaplane. The photograph, at some time has been stored in the "Centre de Documentation Aeronautique Internationale" Paris; (wet stamped to the rear). Designed by Raffaele Conflenti in 1925, two prototype aircraft were built but the aircraft did not go into production. This could be either MM52 or MM53.

The SISA company operated from Trieste to Turin along the River Po and from Trieste to Ancona via Pola (Pula) and Zara (Zadar), then under Italian administration. The CANT 22RI was powered by one 500-hp and two 250-hp Asso engines, enabling it to carry ten passengers. Photo from: Municipality of Trieste
