Named Engineers MKII
No sign of the makers mark on the shell but the MKI liner is by Vero and dated 1939. The sheel is a back overpaint over the original green with a large E for Engineer to the front beneath which is a small K. Under the brim it is named to G. Kipling which I assume accounts for the small K already mentioned.
This helmet was formerly in the collection of one of our regular helmet spods.cool militaria
