The Mauboussin M.120 was based on a 1931 collaboration between Louis Peyret and Pierre Mauboussin, the Peyret-Mauboussin PM.XII, and like it, was a low-wing cantilever monoplane of wooden construction. The undercarriage was of fixed tailskid type, and the pilot and instructor sat in tandem, open cockpits. Mauboussin built a number of prototypes himself, followed by a small series manufactured for him by Breguet in 1934.

One of first M.120s took part in the international touring aircraft contest Challenge 1932, flown by André Nicolle. It completed contest on the last 24th place, but it had the weakest engine of all participants and completing this contest was quite a success anyway.

In 1935 Maryse Hilz set a women's altitude record of 7,388 metres on 24 September in the M.122.

In 1936, Fouga, then a builder of railway rolling stock, purchased all rights to the design as part of an effort to enter the aircraft industry, and was able to secure a contract from the Armée de l'Air to supply the type as the M.123.

The Mauboussin 123 was built 1937-1938.

Production was restarted by Fouga after the war for the French flying clubs.

The Mauboussin M.129 was built 1947-1948.
