It was a single-engine, single-bay, equal-span biplane, slightly smaller than either the Sopwith Camel or Nieuport 17, with a proportionally large engine fairing and tall fuselage giving it a relatively stubby appearance. It was armed with one synchronised 7.7mm Vickers machine gun, mounted unusually on the left-hand side of the fuselage, and fitted with the Vickers-Challenger synchroniser gear, also designed by Challenger. The 100-hp Gnome Monosoupape engine gave a relatively slow speed, and the relatively low cockpit position, placed behind a wide rotary engine and between unstaggered wings, severely limited visibility for the pilot. The clearest view was sometimes said to be upwards, through a transparent section in the upper wing. Modifications were introduced, including a more powerful 110-hp (82-kW) Le Rh\u00F4ne or Clerget engine and staggered mainplanes, culminating in the Mk II design. The plane's relative success on the Eastern Front appears to have been due in part to the fitting of a more powerful engine in in Russia."@en . "The F.B.19 was designed by G. H.
