Only one was built, and it was used for some commercial routes starting in 1935, and later aviation training by the British Royal Air Force until 1940.
The Hall PH was an American flying boat of the 1930s. It was a twin-engined biplane, developed from the Naval Aircraft Factory PN and could hence trace its lineage back to the Felixstowe flying boats of World War I. The PH was purchased in small numbers by the United States Navy and the United States Coast Guard. It remained in service with the Coast Guard until 1944, being used for anti-submarine and search and rescue duties.
The Northrop Delta was an American single-engined passenger transport aircraft of the 1930s. Closely related to Northrop's Gamma mail plane, 13 were produced by the Northrop Corporation, followed by 19 aircraft built under license by Canadian Vickers Limited.
The Curtiss O-40 Raven was an American observation aircraft of the 1930s which was built and used in small numbers.
