Morane-Saulnier MS.472-475 Vanneau — Primary-Source Technical Archive

The Morane-Saulnier MS.472 Vanneau II was the definitive tandem two-seat advanced trainer of the post-war French air forces — a low-wing all-metal monoplane that bridged wartime design heritage with the demands of jet-age pilot transition training. Designed by chief engineer Paul-René Gauthier during the Vichy period and finalised after the Liberation, the MS.472 entered series production with 230 airframes delivered to the Armée de l’Air, spawning a family of naval and experimental variants that served into the 1950s.

This Living Collection assembles the original military mechanic’s notices, naval addenda, the MS.475 hydraulic landing gear technical notice, and Gnome-Rhône 14M engine technical documentation — including the rare BMW Flugmotorenbau wartime German-language edition of the same engine manual — that defined the type’s operational and maintenance life across two air forces.

Every document is an archival, static-copy edition fixed at its original publication date — primary-source material for historians, restorers, flight simulation specialists, and serious collectors.
