WWII French 75mm High Explosive Shell with Original Red and Yellow Paint

[M8owner]

We do not get too many French made 75mm HE rounds on this side of the pond. We get plenty of US made versions with the bourrelet (it is funny how spell checker on the BOCN site wants to show bourrelet as misspelled word) moved higher up on the projectile. This is my new favorite projectile as it retains its original yellow and red paint. I believe that is projectile was made in France and sold to Poland in the 1930's. I have attached a copy of the German manual for captured French ammunition. What is the difference between the yellow projectiles and the red/yellow projectiles? Explosive fill material?
