The photo appears to shown the one and only Vickers 141 between its unsuccessful trials for the RAF fighter and its unsuccessful trials as a carrier based fighter for the Fleet Air Arm. Throughout all these trials it remained registered G-EBNQ, although it did not always display is civil registration. Photo from: Imperial War Museums

The Vickers 141 was created by reengining the Vickers 123 with a Rolls Royce Kestrel in place of the Hispano-Suiza engine of the 123. Unsuccessful in winning an RAF order, it was modified, as seen here, for shipboard use with deck trials in June 1929. It was unsuccessful again. Throughout both trials it remained registered G-EBNQ. The design was developed into the Bristol Jupiter-powered Vickers 143 of which six were built for Bolivia. Photo from: Imperial War Museums
