It was in the process of being replaced, with parachute battalions being issued as priority, when the Falklands War occurred.
The P Type featured a non-magnetic manganese steel shell with a rubberized rim and a lining with interior padding that was similar to the German M36/40 design.
An example worn during the Battle of Arnhem can be found on display in Hartenstein Museum, the Netherlands.
This helmet featured a similar shell design, but with a thick vulcanized fiber band rim that clearly distinguishes it from the German model, along with a four-point chinstrap system and a band of sorbo rubber for padding.
The wartime chinstrap had brass ends and rivets: these were manufactured in blackened steel in the 1950s (in line with production of the 1937 Pattern web equipment at that time).
