This is the first addition to Patent FR-1911-429224, which initial brevet was filed 1911-05-02.
- In earlier editions of the data, this addition was mistakenly associated with the number 427429. Aéro-Manuel 1914 may have given us cause to do that, but FR427429 turns up something non-aero on Espacenet, whereas all comports well with Patent FR-1911-429224.
- Original title=1er certificat d'addtion au brevet pris le 2 mai 1911, pour perfectionnements à la construction des aéroplanrs par l'emploi des pièces en tubes d'acier
- English title=1st certificate of addition to the patent taken, 2 May 1911, for improvements in aeroplane construction by way of steel tubes
