A First War Mark I Tanker's Helmet
Early-issued version of the infantry helmet. British-made, steel, non-magnetic, in brown, smooth finish, with a raw edge and a hole drilled through the top. There is a reinforced magnetic, die-cut steel panel extending from one side to the other, the panel held in place by the tabs of the rivets holding the chin strap loops in place. It comes with a wire that extends the distance between the two loops on the underside of the helmet, the wire fed through the panel in three locations, one on either side and one at the front, securing it to the sub-structure of the helmet, the wire itself fed through twelve loops of the chain mail, suspending the remaining chain mail to a depth of 70 mm, with stands hanging from either side. This enables the chain mail to dangle in front of the wearer's eyes, in order to protect him from various pieces of shrapnel while in battle. There are raised hooks placed on either side on the exterior of the helmet, the hooks slipped under the rivets holding the underlying chin strap loops and facing towards the back of the helmet, enabling the chain mail to be lifted up and the ends of the strands of the chain to be looped around the hooks, keeping the chain mail out of the visual range of the wearer when not in use. The helmet is missing its steel-framed cradle, blackened canvas liner and leather chinstrap, with the maker's stamps having worn off. There would have been no rubber ring in the dome, indicative of the early Mark I version of the helmet, as it was not issued as part of the helmet's construction until the design of the Mark II version. The helmet measures 300 mm x 313 mm x 120 mm, with multiple small dents on top, exhibiting slight pitting on the exterior, surface rust present on the steel panel and on the inside overall, as worn.
