The civilian designation of the Airbus was P-200 or P-200A if it was on floats. The C-27 designation was given to the versions operated by the Army. The C-27 shown in the USAAC markings was the Y1C-27, which had a large cargo door that other later C- 27's did not have.

    The Aircruiser in USN markings is most interesting. If you look closely, you'll see plexiglass windows around the top of the fuselage. So, you may have stumbled upon a photo of the proposed 1932 USN Scout version of the Airbus, the Bellanca SE, which the Navy tested briefly in 1932, but did not accept.
