Yes, this is the one, the picture is from Trait d’Union no.209. I suspect that the M-1 was the Atlantic project, and the M-2 was the military version.
It was actually harder than I thought, it is one of those French makers about which very little was published.

Nobody? There is a clue written on the tail of this French flying boat…

This aircraft looks similar to the FVA-18 Primitiv Krähe designed by the Flugwissenschaftliche Vereinigung Aachen (founded in 1920 too):

But there are also differences with the photos linked above. It seems that this aircraft was modified several times during its career, this might explain.

Yes, this is it, from Flight 27 Jan. 1927.
Your turn!

Hi,
It’s the prototype Breguet 27, a perfect example of classic French elegance…

Hi,
This is the correct country. Juan de la Cierva made a three-engined biplane for the same 1919 competition, in the bomber category. This one competed in the observation category, and was made by the country’s third largest aircraft company. It does not seem to have a proper name, only that of the designer.

About #293: this is a South European design, built in 1919 for a program calling for homebuilt military aircraft.

Hi,
Let’s try this one:
