Dear Adrain:
There must be enough free models out there on the internet to be of use for your group. many museums have and use a one page model for kids programs, how long of a lead time do you have before your date for the program? I don't do much in WW1 I will look in my files for some that I squrraled away of the rainy day. Look at this one here
