Here I have a Mk IV helmet made in 1952 and converted for use as a riot helmet and probably used in Northern Ireland during the troubles. You can see on the pictures the date 1952 and Mk IV but unable to see maker mark as it has been repainted and textured over where the maker mark probably is. The helmet has had a 3 point suspension added to give the helmet extra stability on the head. The suspension is dated 1972 and has the military broad arrow mark. The liner is also dated 1972 on both parts of the liner. The helmet shows a fair bit of scuffing to the top of the helmet and the visor. This helmet had well over 25 years of service with the British army and I wish it could talk Thanks for looking guys and please feel free to add anything I may have missed out.
