Hello. I’m looking for opinions on this unusual Ww1 brodie helmet. Colour is a brown and green pattern with appropriate aged patina. Also has a white stenciled "d" on the front and "200" stenciled on the back inside shell. Solid liner with red patent stamp. Can anyone identify the markings and unit? I have an opportunity to buy it but don’t know exactly what it is. Than you. KD
