horse drawn artillery has played a major role in the defence of Holland May 1940, and did great work to hold off the Germans with the materials they had. No they had not the same fat as the polish. (Horse VS tank)
There were barracks next to Airport Ypenburg and was bomed and 65 men and more then 100 horses died.

About the helmets.
I know there are no dutch helmets in lego size ...... And if there where WW1 brodie helmets i could use them as an alternative for the Dutch M16 helmet.
