The Les Ailes article is good and detailed but does not say when the Potez flew or (of course) anything later. There are only 4 other significant mentions in all the Bibliothèque Nationale's digital data base and they give no clues either as to first flight date or engine type.The web sites all agree it was a 12Mb, though not necessarily all the time. This was a V-12. However, Les Ailes is clear that in mid-1928 the 31 had a 500 hp Hispano-Suiza W-12, so that would be a 12G or 12Ga (as used on the Potez 25). At the risk of OR, I've put that in. Fr:Wiki half suggests this (12Mb/Ga?) as well two other engines; the use (or intention of use) of a Lorraine Pétrel is supported by the link [gallica.bnf.fr/ark:/12148/bpt6k7595858m/f2 here], from the 1934 (late) Paris Salon. Not really enough to use, though. I suspect that Coroller and Ledet's book, cited by Fr:Wiki might shed some light but I don't have it.
Strangely, the two other newspaper reports are from the later1930s, when I assumed the 31 was dead and gone, [gallica.bnf.fr/ark:/12148/bpt6k7584584g/f7 this one] 2 (!) in N. Vietnam and [gallica.bnf.fr/ark:/12148/bpt6k5765922k the other] at Djibouti. Cases of mistaken i/d? TSRL ( talk)
