Émile Chesnay, a photographer and balloonist, had a monoplane built by Clement Bayard. It was equipped with a Clerget engine of 50 hp. The wings, with a span of 8.50 m resembled those of Bleriots and may have been built at their factory. The landing gear had two wheels and two curved skids. It was presented at the aviation meeting of Dijon which was held from 22 to 25 September 1910.
