The centre wing section was attached to the fuselage by six bolts.

A batch of 13 A-33s were delivered to Peru by the USAAF. Camouflaged example at la Palmas Air Base, Lima, in 1959. It is most certainly one of the very last flying aircraft of the type.

Peru ordered ten Model 8A-3Ps, this example photographed before delivery on December 12,1938. Note that the Northrop insignia has been retained on the fin but it reads Douglas.

An Argentine Model 8A-2 awaiting delivery. Argentina purchased 30 aircraft and the type was operated until 1955.

The detailed story of the Iraqi Northrops is not known but they were most probably destroyed on the ground by RAF aircraft in 1941.

ASJA-built B5s were recognisable by the front-mounted antenna mast and bubble canopy.

A total of 61 ex-French aircraft were handed over by the RAF as Nomad Is. AS441, shown here, was the second of these aircraft. Most of them were delivered to the SAAF. Note the exhaust stack.

The multicellular wing of the A-17 inherited from the famous Northrop Gamma permitted the easy installation of fuel tanks.

The Model 8A-3Ns were delivered to the Netherlands in October 1939. Up until the end of the year, they were painted with the Dutch insignia as used from 1920, an inverted orange triangle outlined in black.

Thanks to the semi-monocoque construction, the fuselage was both light and robust. Fuselage interior behind the rear cockpit. Command cables and pulleys are evident.
