Hi,

Mr. Roger Dupuy was a French,and he burn in 1899,and he worked for
many companies,in 1933 he designed the D-40,a single seat low-wing
tourist and light monoplane,powered by one 40 hp Salmson engine.

As they mentioned in Trait d'Union issue 194,he also designed a D-50 and
D-60,I don't have this one,and as I suggest they were a Projects,has anyone
a more Info about them and if they were built or never ?.

Another shot of the Dupuy D-40.

Caption reads: "January 25, 1934 - Seen in Marignane, the amateur-built Roger Dupuy D40 F-AMUQ aircraft in which Etienne Chartoire called at Collo and Bône while attempting to remove the Coupe du Président on the Paris-Saigon route. Injuring his hand with his propeller, Chartoire will continue on 'as a tourist' to Saigon. A month later, on return, the plane will burn at Calcutta. (Henry Dupuy)"

From TU 224,

Mr. Dupuy designed an ultra-light monoplane or a biplane,powered by one
11 hp Indian motorcycle,and the airplane could be a single or two seat,of
course remained a Project,1933,and maybe it was D-30 ?,need confirm.

From TU 194,

On the other hand, in 1933, he produced the D-50, a cheap single-seater
fitted with a Salmson 9 Ad of 40 hp. It will be registered F-AMUQ. At the
end of 1934 the D-60, derived from the D50,will be studied and produced,
but I think it remained a Project.

After that,we can say;

D-10 ? maybe it was a six passenger commercial seaplane Project of 1931
D-20 ? maybe anther seaplane Project,definitely a civil airplane,1931
D-30 ? maybe it was an ultra-light monoplane or a biplane,powered by
one 11 hp Indian motorcycle,1933
D-40 was a single seat low-wing tourist and light monoplane,powered by
one 40 hp Salmson engine,1933
D-50 was a cheap single seat light monoplane,powered by one 40 hp
Salmson 9 Ad engine,1933
D-60 was a developed version of D-50,remained a Project only as I guess
