It's the Dewoitine D.4

An 1/25 scale model of this plane was shown for a "Salon de l'aéronautique" in Paris in 1921 (12th-27th november). F-ATMA 2 was a fictionnal french identification (Aéro-Transports Méditerranée Atlantique). The project was too expensive for M. Ernoul (owner of the too little "Aéropublicité" company) and for M. Dewoitine too (the D.1 fighter needed a lot of money).
-engines : 2 x 230 hp Salmson Canton-Unné Z 9
-Length : ?
-span : 22 m
-wing area : 65 m² (with the first 21,5 m wing)
-weight max : 2990 kg
-speed max : 200 km/h (2000 m)
-passengers : 8


A D.11 of 1923 was a possible bigger derivative of the D.4 (2 X 300 hp Hispano-Suiza 8 Fb, for 10 passengers)


There was a night bomber (Bn2) derivative project of the D.4 too :
-engines : 2 x 230 hp Salmson Canton-Unné Z 9 (later : 2 x 260 hp Salmson Canton-Unné CM 9)
-length : 13,1 m (later : 14,4 m, then : 14,5 m)
-span : 21,8 m (later : 22,22 m, then : 22,3 m)
-65 m² wing area (at first)
-weight empty : 1730 kg (later : 1850 kg, then : 2115 kg)
-weight max : 3230 kg (later 3570 kg)
-max speed : 210 km/h (2 000 m)
-bombs : 10 x 50 kg

The Bn2 programme was abandonned (mid 1924 ?) and the D.4 Bn2 prototype never finished.

This was a 1937 project that seems to be similar to the D.342, which itself was a development of the D.338. Any further information on the D.341 would be appreciated.

Hi! D.750.
https://en.wikipedia.org/wiki/Dewoitine_D.750

"The Dewoitine D.750 was a prototype French twin-engined torpedo bomber. It was designed prior to the outbreak of the Second World War to operate from the aircraft carriers of the French Navy, but only a single example was completed, with development ended by France's defeat by Germany in June 1940."

Hi! D.513 and D.514.
https://en.wikipedia.org/wiki/Dewoitine_D.513
"The D.513 was a single-seat low-wing cantilever monoplane fighter that first flew on 6 January 1936. The D.513 was powered by an 860 hp (641 kW) Hispano-Suiza 12Ycrs1 inline piston engine and had a retractable tailwheel landing gear. Testing proved that the D.513 was unstable and not able to reach the expected speeds and it was rebuilt with a new fuselage and a modified tail unit. The changes did not improve the stability or the maximum speed and problems were also found in the engine cooling and landing gear, and further development was halted. The second prototype was modified with landing gear and a radiator from the D.503. It was redesignated the D.514LP and was used in high-speed parachute trials."

Hi! Dewoitine D.560 and D.570.
It's very hard to find D.560 three side view drawing with radiator fairing(bottom picture).
Also it's very hard to find D.570 three side view drawing.

https://en.wikipedia.org/wiki/Dewoitine_D.560
"D.560 Prototype gull wing fighter, one built. D.570 The D.560 rebuilt with a parasol wing."

Hi! D.520 prototype and D.520Z.
D.520.01 radiator design is different from other models.
D.520Z radiator moved forward direction.

Hi! D.33.
https://en.wikipedia.org/wiki/Dewoitine_D.33
"The Dewoitine D.33 was a single-engine low-wing monoplane aircraft built by the Dewoitine Company. It is remembered for setting a long-distance record on its first flight in 1930.
Little is documented on the specifics and the basic model of the D.33, other than the fact that it had a fixed undercarriage, and was a low-wing cantilever monoplane. There were three documented variations to the model, each of which was designed as a separate aircraft. This line of aircraft were regarded highly commercially before World War II, and they were influential in the establishment of the Dewoitine Company."

Yes. What a pity. :'(
"On January 15, 1934, while flying from Lyons, France, to Paris-Le Bourget Airport outside Paris – the final leg of a flight that began on 5 January in Saigon, French Indochina, with stops at Karachi, British India; Baghdad, Iraq; Marseilles, France; and Lyons – the prototype Emeraude, operating for Air France and registered as F-AMMY, crashed in a snowstorm at Corbigny, France, killing all ten people on board. The crash probably occurred due to icing."

Hi! Dewoitine D.511,503 and AXD1.

http://aviadejavu.ru/Site/Crafts/Craft33646.htm
"In the centre of this display is the Breguet 46T as it will look when finished. Two Mistral Major engines of 880 h.p. each are expected to give it a top speed of 240 m.p.h. In the foreground is the Dewoitine D.511, France's latest and fastest fighter."

https://weaponsandwarfare.com/2015/08/18/dewoitine-d-510/
"D.511
Prototype with D.500 fuselage and tail, smaller wings, cantilever undercarriage, 12Ycrs engine. One prototype built in 1934 but never flown, converted to D.503."

"D.503
The sole D.511 prototype fitted with a 12Xcrs engine with a circular radiator in the nose, the same armament as D.501. First flight 15 April 1935, found to perform worse than D.500. The aircraft was briefly the personal mount of René Fonck."

"AXD1
The short designation for the single Dewoitine D.510 supplied to the Imperial Japanese Navy Air Service for evaluation in 1935."
