These are the only genuine S.55 parts remaining in Italy of some 240 of these impressive double hull flying boats. A formation of 24 S.55X completed an 18600 km Atlantic round-trip to the USA in 1933, after 14 S.55TA flew to Brazil in 1930-1931. On display are the central part of the left hull, a tail rudder and an engine. The hull still shows partial markings of the 199a Squadriglia, 94° Gruppo, based at Orbetello.
