De Monge projects

All right, I will check and scan and post the forthcoming week-end. For the items with just a Mention, it will be even more simple: I just have to translate into English without scan. Soon.

Yes, this aircraft was registrated for the 1921 Coupe Deutsch but crashed on September 23, 1921, following a flutter problem.
Pilot De Romanet was killed.

Source: Book "The Speed Seekers" by Thomas Foxworth.
"During 1921 Viscount Louis Pierre de Monge de Franeau, owner, general manager and directeur technique of Etablissements Lumiere...decided to enter that season's major European air races with a new speedplane...his avion de course designated 5.1..."

Note: In the book is mentioned that prior the race, "De Monge was already at work on the design of a tailless flying wing, a type whose popularity was suddenly burgeoning."
Any information about this tailless flying wing design?
Thanks in advance,

I start from the end of the Trait d'Union collection, to get corrections before mistakes.
#175:
In 1922 Show was presented the Buscaylet-De Monge 5-2 fighter and a drawing of the 3-engined 7-2 (9000kg weight plane for 30 passengers on 1000km distance at speed over 200km/h).
Louis-Pierre de Monge de Franeau was a Belgium citizen, born in 1890 and deceased July 25th 1977 in New York. He built his first airplane in 1911. He worked during WW1 for the Lumière company. After the war, he stayed technical director for Lumière while creating his own design bureau. He designed and built many machines in France. After the failure of them, he went and worked in Belgium for Imperia. In 1937, he has been the designer of the Bugatti racer for the Deutsch de la Meurthe Cup.

From "Le Trait d'Union" #171:
The Type 120 of the Exino company founded by Louis De Monge was a 3-seater for night reco. A derivative with 2 engines of 400hp would have reached 230km/h and 7,000m (instead of 200km/h and 5,700m). The program it was competing in was canceled in 1932. The 120 never flew and the Exino Co. disappeared.

“Le Trait d’Union” #171:
- The Exino company created by Louis De Monge presented in December 1930 a project Type 140, three-engined airliner with inhabited wing. Weight 18 tons, power 2,000 hp total , flying at 230km/h 5,000m.
- A mock-up has been built in 1931 of a BN-4 class “flying wing” (like the Type 120). 245km/h 7,000m. Cancelled because the company disappeared.
- In 1935, De Monge designed a small 2-seat “flying-wing”, to be constructed at Starck and Guénot Co. With a Rubis-Péquignol engine.

“Le Trait d’Union” #164, texts without picture:
- Type 6.1: designed in 1921, amphibious with hull for 15 passengers, Paris-NewYork line (imagined…). 3 engines of 500hp. Looking like the Richard Penhoet 2. Not built.

Excellent my dear Tophe,

thank you very very much,and can I ask about two aircraft,
the first 8-1 CN2 and what is that mean,two-seat naval fighter
or not,and the second 9-1,I think it was submitted to 1923 C.1
competition.

[Tophe]

and can I ask about
the first 8-1 CN2 and what is that mean,two-seat naval fighter
or not,

According to http://www.aviafrance.com/aviafrance1.php?ID=3749
it seems a CN2 is "un Chasseur de Nuit biplace" (a 2-seat Night Fighter)
