The Bristol 118 prototype first flew in 1931. It wore Bristol test registration R-3, regular registration G-ABEZ and military serial K2873. After re-engining with the new Bristol Mercury radial it underwent hot weather testing in Iraq. A second prototype, R-6, was fitted with a novel gun turret and designated Bristol 120.

Developed from the Bristol 118 general-purpose military aircraft, the Type 120 featured an enclosed, rotating turret for the observer/gunner. First flown from Filton on 29 January 1932 with the test registration R-6, the prototype was evaluated by the RAF at Martlesham Heath later in the year as K3587. Despite their good characteristics, only two Type 118/120 aircraft were built. Photo from: Bristol
