Canon de 75 modèle 1897 (yes that says 1897 and yes it was used in the first world war)French field gun, the 75mm quick firing gun that seems to have appeared in service with every country the germans invaded (used by the poles and czechs)
Canon de 105 mle 1919 Schneider; again french but this one is a 105mm howitzer,
Both were also used by polish forces in the second world war, having ben donated to them by france to aid them in the fight against communists.
Laffly S15, french light truck. maybe this could be converted into a french suppy truck? also used to tow the above guns.
