Breguet 19.7/8/9/10
Breguet 19.7 - Five Yugoslav Breguet 19s (which version?) were returned to Vélizy-Villacoublay for modification by Breguet. They were fitted with semi-elliptical wingtips, span being increased to 49 ft 2 1/4 in (14.99 m), length to 31 ft 6 in (9.6 m) and wing area to 530.46 sq ft (49.28 sq m). Four additional support struts were fitted between the fuselage and upper wing. The five aircraft were also re-engined with the 600 hp Hispano-Suiza 12Nb and redelivered to Yugoslavia in 1930. 99 Yugoslav Breguet 19.7s were put in production at the Kraljevo works (5th production batch from Frabrika Aviona Kraljevo), though a shortage of Hispano-Suiza engines meant that only 51 had been completed by 1933.

Breguet 19.8 - A single Yugoslav Breguet 19.7 (No.1243) was tested by Breguet with a 690 hp (515 kW) Gnome-Rhône 14Kbrs radial engine. Further tests in Yugoslavia led to its rejection as a possible powerplant for the 48 engineless Bre 19.7 airframes, and it was finally decided to fit the 780 hp (582 kW) Wright Cyclone GR-1820-F-56 9-cylinder radial engine with a Hamilton propeller. The 48 aircraft were completed accordingly, the last one delivered in November 1937. Total of 99 Breguet 19.7/19.8 aircraft - all FAK built. In April 1941 the Army Air Force operated 38 Bre.XIX-7 and 48 Bre.XIX-8. Many were captured by the German Army and 50 were transferred to the Croatian Air Force.

One Breguet 19.7 converted to Breguet 19.9 with Hispano Suiza HS 12Ybrs engine. One Breguet 19.7 converted to Breguet 19.10 with Lorraine Dietrich 12Hfrs engine.
