This is an addition to Patent FR-1911-427852, which brevet was filed 1911-03-28.

Additionally this document offers « Certificat de garantie délivré le 30 décembre 1911 à M. Brauer, à l’occasion de la 3e EXPOSITION INTERNATIONALE DE LOCOMOTION AÉRIENNE ouverte du 16 décembre au 2 janvier 1912. – Déclaration du déposant. » No similar reference is made on the parent patent. So this « Certificat de garantie », whatever its legal significance, was delivered during the exposition and predates the filing of the addition itself, that is, according to the testimony of the inventor.

We will likely be fleshing more out on these administrative and other particulars on Exposition de la Locomotion Aérienne.
