Hi,

Mr. Léon Lacroix was a French designer,he associated with a numbers of other designers to
create a light airplanes,most of them were very similar in conception to Mignet Pou-du-Ciel.

He began with Barret de Nazaris to develop a LN-1 Autoplan,a single seat tandem monoplane
tourist light aircraft,powered by one 32 hp engine,followed by the same idea,the LN-2 & LN-4,
but the later was different a little,the LN-3 was a single seat tourist biplane,powered by one 40
hp engine.

Barret de Nazaris alone,developed a glider looks like Elytroplane shape,maybe called N.5,the
N.6 was a single seat pusher tandem monoplane Project,later the N.7 was a single seat tailless
pusher airplane,and the tail fins mounted almost at the tip of the wings,also remained a Project
only.

but the anther pusher biplane Project,maybe called N.5 ?.

Proposed translation:

N-5 Autoplan
Fully designed by Barret de Nazaris, this machine had a span of 6.7 m (front wing), was strongly built (300kg empty, that is a lot) in spruce and plywood. Engine: Train 40 cv. A number of building tricks was included to help amateur building. We do not know it if actually flew.
Front span: 7m, rear span : 5 m, lenghth: 4.6 m, area: 12 m², empty weight: 210 kg, full weight: 385kg, engine: Salmson 9 Ad, 40 cv

During WWII, Barret de Nazaris built a glider whose vertical stabilisation concept was similar than the one used in elytroplans. Unfortunately, due to various defects (centering too backside,towing speed too high, bad use of elytroplan principle), this machine was damaged during fisrt flight. Barret de Nazaris broke his leg.

I don't think so because the text tells about a glider and the dawings shows the cicle of a propeller at the rea.

What's more, the drawing bears no resemblance to an elytroplan. Contrast it to any of de Rougé's designs, or those of his followers, and the difference will be evident.

Yes my dear Avion,
