The Bernard 74 was developed in 1931 and hence makes a suitable tier-1 aircraft for the French tree.  Another good candidate could have been the Nieuport-Delage NiD-62 (as posted by Roudou).

Let's compare them.
Bernard 74----------Nieuport
Development:    1930----------1931
Speed: 310km/h----------270km/h
Armament:   2 7.7mm----------2 7.7mm

Two versions of the aircraft were built, but the aircraft never went beyond prototype status.  The French Government ordered 25 aircraft, but the company went bankrupt and the remaining 23 aircraft were never produced.

Design and development (source facebook)
The Bernard S-72 was a wooden stressed skin constructed cantilever low-wing monoplane powered by a Gnome-Rhône 5Bc radial engine and had a fixed tailskid landing gear. Flown by Paillard the Bernard S-72 participated in the 1930 Coupe Michelin race. On 29 June he took off from Le Bourget, landed successively in Reims, Nancy, Strasbourg, Dijon and Clermont-Ferrand, but unfortunately had to retire near Lyon as a result of engine failure. The S-72 was re-engined with a Gnome-Rhône 7Kb and re-designated the Bernard S-73. The S-73 was then developed into the Bernard 74 single-seat fighter and retained the Titan-Major engine. Two prototypes were built with the first flying in February 1931, powered by a 280hp (kw) Gnome-Rhône 7Kbs radial engine, the second was fitted with a 360 hp (268 kW) Gnome-Rhône 7Kd engine and first flew in October 1931. The first prototype 74 was re-engined with a Gnome-Rhône 9Kbrs radial engine and re-designated the Bernard 75 it was later used as a pilot-trainer. No further aircraft were built.
