Great condition! Being an engineers helmet may have helped it survive in such pristine condition, not seeing the hard life of the trenches. I have one that has some of the combat finish left, a heavy sand impregnated paint, although most of it had rubbed off over the years revealing it's original finish.
I'm currently in the 33rd i found this thread on Google, it'd mean alot to me if anyone has 33rd gear from ww1 or 2 for sale. Thanks.
