Gas Mask Canister Bottom Spring – 'Bodenfeder'

Gas Mask Canister Bottom Retention Spring – 'Bodenfeder'. German Wehrmacht gas mask canister bottom retention spring. Designed to sit securely inside the very base of the Tragbüchse 38, this spring functions to keep the anti-dim cloth flat and protected against the bottom of the tin, preventing them from shifting under the weight of the mask. The piece remains entirely solid with excellent structural tension and flexibility, showing only minor age-related surface patina. A highly useful and frequently missing accessory, ideal for completing or restoring an incomplete combat gas mask set.
