This set is composed of reproduction and material made after war.
It consists in:
A gas mask similar to the M5 model,
An M7 waterproof cover,
A gas detection armband.
This set was used by paratroopers during the jump in Normandy, as well as by the first units to have landed on the beaches. Thus, it is not uncommon to see the gas mask worn in its cover M7 on many shots of the 82nd and 101st airborne divisions, as well as the 1st, 4th and 29th infantry divisions.
