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.
