Hi !!!
Sorry it's my fault ,I haven't checked with other books.
The wingspan is really too big.I think there is a mistake in info in the publication.One of Breguet 19 version called Super Bidon was a special plane to for long range flights.Its lenght and wingspan were bigger than standart ones.Therefore the autor could be wrong about it.I think that info on its machine gun could be also a mistake. I'll check it.
There is another info I've found.
Breguet Bre.19.7 - Five Yugoslav Breguet 19s 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 (447 kW) Hispano-Suiza 12Nb and redelivered to the Yugoslavs in 1930. Five similar aircraft bearing the same designation (Breguet Bre.19.7) were delivered to Romania. All 10 aircraft participated in the Petite Entente military aircraft competition, the Yugoslav Bre.19.7s doing particularly well. 125 Yugoslav Breguet 19.7s were put in production at the Kraljevo works, though a shortage of Hispano-Suiza engines meant that only 75 had been completed by 1933. A number of these Yugoslav Bre.19.7s took part in the brief resistance to the Germans in the spring of 1941, several being later used by the Croat regime. The Turks ordered 50 Breguet 19.7s in 1933, and these were the last of the Breguet 19 family to be built by the parent company. Maximum level speed of the Breguet Bre.19.7 was 150 mph (242 km/h).
Breguet Bre.19.8 - A single Yugoslav Breguet Bre.19.7 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 50 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 50 aircraft were completed accordingly, the last one delivered in November 1937, and a handful survived to be used by the Croat regime after the Yugoslav collapse in 1941. Maximum level speed was 173 mph (279 km/h) at 8,200 ft (2500 m).
