The American Aeronautical Corporation, founded by Enea Bossi, produced the S.56 amphibian for the American market at Port Washington, Long Island, and this looks like the place. NC897W is not listed as an S.56 in the Golden Years Register. Apparently the registration was first used by an Albert TE.1 which was cancelled in September 1930. The Port Washington site was sold to Pan Am in 1933. Bossi also built a stainless steel variant of the S.56, the Budd BB-1 Pioneer.

Later renamed Bermuda Clipper. The S-42 was used mainly on Pan Am's Miami - Rio route. Pending the completion of the Marine Air Terminal at New York - LGA, the modest Port Washington facility on Long Island was used for Atlantic flights, although revenue services only reached as far as Bermuda until the Boeing 314 became available just before WWII.

The S.23 flying boats lacked the range to cross the big pond with payload but a limited route was opened between the British territory of Bermuda and New York or Baltimore. Cavalier was actually shipped to Bermuda. Suffering icing, the aircraft ditched en route from NY - Port Washington to Bermuda on 21 January 1939 and three of the 13 people on board lost their lives.

During the 1930s and 1940s there was a New York Seaplane Airport outside the city in Port Washington, Long Island. Both Pan Am and Imperial Airways used it pending the completion of La Guardia's Marine Air Terminal. Their Sikorsky S-42 and Short Empire class flying boats didn't have enough range for transatlantic services and only proving flights were made, although a limited commercial service was started between Bermuda and New York.
