Kev wins again, ist a DH9, this time the air-ambulance version. The DH9 was pretty useless as a fighting aircraft and at the end of WW1 were modified for load carrying purposes. For the ambulance role, a special installation was built behind the cockpit over the former gunner's position in the widest part of the fuselage, where it was possible to fasten stretchers keeping the injured in a steady position. The construction of the fuselage itself was little changed, there simply appeared a prominent fuselage fairing. Only a single machine of this variant was built, and its operational use was short, because from the mid 1920's more capacious ambulances were produced, converted from more modern twin-engined bombers or transport airplanes.
