The company Société des Moteurs Salmson was established to produce aero-engines, especially Canton-Unne water-cooled radials. In 1916, built S-M biplane with shaft drives to two tractor propellers, the M standing for its designer, Lt. René Moineau. From January 1917 built some 3,200 conventional armed reconnaissance biplanes; post-war several dozen were converted to passenger aircraft. Company appears to have stayed in business to sometime beyond WWII, intermittently producing aircraft.

It would appear Canton-Unne was designed by Canton-Unne. Did Salmson have a license or was it a subcontractor? (Voir Canton et Unné.)

We have records from 1920–4 of patents filed by Pierre-Jean-René Postel-Vinay who worked on Canton-Unné system motors and assigned his patents to Moteurs Salmson.

This source, citing a book about Moteurs Salmson, indicates that Henri Salmson, not cited in our sources, was a key character in hiring Canton and Unné.[1]
