The Latécoère 3 was a French biplane transport; the 1919 prototype was a two-seater but the unbuilt production version would have carried two or three passengers as well as the pilot.
Immediately after the end of World War I, Pierre-Georges Latécoère began his career in aviation by building limousine versions of the Salmson 2 and of the more powerful Breguet 14, both French wartime two seat observation aircraft.
The limousines replaced the open rear observer's cockpit with seats for two passengers, enclosed in a hump roofed, windowed cabin.
[1] By the end of 1919 Latécoère had built a new and original design, which appeared at the Paris Aéro Salon in December of that year.
The intention was to provide the Latécoère 3 with a similar limousine type, two or three seat passenger cabin with space for post to be carried at the rear, though this was never built; the Salon machine had two open cockpits with the pilot in front, as on the unmodified Salsmon.
