For other machines it is likely that Berthaud was the builder and financial partner - cf Melin.
Moreau-Berthaud: Associated with a Moreau (not the famous Albert Moreau), Berthaud built this monoplane similar to the early Sommer design: an uncovered fuselage, possibly made of steel tubing; Bleriot-style inverted-V cabane struts which ran down to the skids which in turn supported the wheels. It was powered by a 50 hp 2-stroke double-acting 4-cylinder radial Berthaud.
Berthaud Monoplane W: Designed and built in 1911-12, this successful machine was referred to as a Berthaud, in fact designed by Pierre Wroblewsky - who with his brother Gabriel were known as the Salvez brothers! Like a former Salvez design of 1909, the W was based on the Antoinette model, but of metal construction, with 2 seats in tandem; the engine was mounted at the front of the triangular-sectioned fuselage whose aft end was diamond-shaped; a small steel ladder was attached to the port mid-fuselage longeron for easy access to the cockpit. In 1913 the Monoplane W was mentioned in flight reports at Amberieu, and on 1 Mar 1914 Gabriel Wroblewsky was reported "killed in the crash of a monoplane designed by his brother Pierre, who was injured," after a wing broke off. The boy Antoine de Saint Exupery took his first flight in one of these machines.

From 1912 to the start of the War, Berthaud worked with Moreau at building automobiles in Vincennes under the trade-mark Moreau-Berthaud or Moreau-Luxior.
