US/ British airborne ww2 gas sleeve armband 1944

Ww2 gas sleeve armband, used by the British and the Armerican paratroopers. The sleeve changes colour when in contact with gas. The sleeve is in a excellent condition and has all of the original gas detection paint left on the paper and is nicely dated 1944. Original sleeves are very hard to find and especially in this suppreme condition. Great to upgrade your assault display
