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,

Hi,

The De Monge 5/2 was a single seat fighter fitted with a parasol
wing as a monoplane,it was flown first time in 1923.

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.

By this time (1924),the De Monge was associated with Buscaylet, and of
course it was not a fighter,but may be a racer or experimental aircraft.

Here is a selection of previously unshared documents related to the Lumière-de Monge racer. The aircraft was to be raced by pilot de Romanet during tests, but he died in a crash after the fabric of that aircraft covering peeled off in flight.

Aerial Age called it the Type 5A in November 1921, and it's interesting because French publications of the time didn't give a designation for it. Of course, it is known in all later sources as Type 5/1, but that designation may have been applied in retrospect by Buscaylet when de Monge joined Buscaylet's company as a partner after his Établissements Lumière took a blow, and the Type 5/2 was designed.
