Morane-Saulnier M.S.131
The Morane-Saulnier M.S.131 was the designation given to a single M.S.130 parasol wing trainer that was fitted with a 230hp Lorraine engine in place of the 230hp Salmosn 9AB radial engine used in the original aircraft. The M.S.131 was flown by the US military attaché in Paris.
