Many thanks everybody for all those great comments !
The figures from guilhem were more easy to paint than the SHQ figures because the details and faces are more neat, but with more work you can't see the difference !
The french 75 gun is from Alby miniatures, for those who want to complete their set of Legion
you can find it here (ref 1001) :http://albyminiatures.e-monsite.com/pag ... rance.html
"1001. Canon de 75mm Bir-Hakeim surbaissé des FFL/ FFF dropped A-T gun"
But of course you can replace them by some british or US gun, it work as well for many others battle.
