René Fonck - 16 conf. + 8 unconf. (according to Christophe Cony; David Méchin identified 16 conf. + 5 unconf.; we have to wait probably a few years for Ch. Cony's biography of Fonck...)
Georges Guynemer - 4 conf. + 1 unconf.
Georges Madon - 2 conf. + 1 unconf.
Joseph Marie Xavier de Sevin - 2 conf. + between 1 and 3 unconf. (needs more research!), maybe more
Armand de Turenne - 1 conf.
Francois Battesti - 1 conf., maybe more?
Gabriel Guérin - hard to say (0 - 2 - more?)- if D. Méchin's suggestion that his victory at 10:35 on February 3rd 1918 could have been scored on SPAD XII is right, then also his second victory on that day (5 minutes later) must have been scored on SPAD XII
Marcel Hugues - most probably 0 (surely not more than 3)
Benjamin Bozon-Verduraz - 0? (surely not more than 2)
Albert Deullin - 0 or 1 maximum (only his last victory could have been scored on SPAD XII, but no info)
Henri Hay de Slade - probably 0 (didn't like this plane)
Big question is about
Charles Nungesser - used SPAD XII for sure, many SPAD victories, but we don't know which type
Fernand Henri Chavannes &
Lionel de Marmier - no idea, from 0 to a few!
David Putnam,
Charles Biddle &
Georges Raymond - 0 for sure
