FBA 19

The FBA 19 was a flying boat bomber developed in France in 1924 by Franco-British Aviation.
Design.
Similar in configuration to FBA's wartime designs, it was a conventional biplane flying boat with open cockpits for the three crewmembers. Unlike the firm's earlier designs, however, the engine was mounted tractor-fashion in a streamlined nacelle mounted in the interplane gap. 
Operational history.
The prototype set a world altitude record for its class with a 500 kg payload, but despite this performance, the French Navy did not order it, either in its original form or when it was offered as an amphibian. Another version was built as a commercial transport, but the only example built was sold to Air Union.
