Merci, Patrice. Vos renseignements supplémentaires étaient très utiles.
Armed with the description, the Moreau Model 10, the internet became my friend! There is much more about it at http://www.master194.com/forum/viewtopic.php?f=3&t=68377, including a much better image (reproduced below) and at http://wingsofintent.blogspot.fr/2012/05/delanne-ii-moreau-jm-10.html. Does anyone have a copy of issue no. 68 of Avions, in which it is said is an article on this aeroplane by Pierre Cortet?
It would seem that this aeroplane started life at the Delanne II F-AJGB; was sold to SCA and renamed the SFR-10; and was then sold on to Jean Moreau, becoming the Moreau JM-10. After the involvement of Nicolas Payen, several engine changes and re-registration as F-ANNI, M. Moreau apparently tried to sell the JM-10 into Spain, at the time of its civil war, was murdered and the aeroplane was heard of no more!
