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.
