WWI M1917 Small Box Respirator Full Kit

World War One US M1917 Small Box Respirator Full Kit. This full respirator kit is in near perfect condition and contains the canvas carry bag, the instruction manual, the anti-dimming stick, a spare respirator tube, and the respirator/filter canister still attached to the gas mask. The canvas carry bag has only suffered from minor discoloration over time. The exterior of the top flap is marked with a large “4”. The body of the bag and interior of the top flap are marked “768466”. The interior of the top flap is also marked “S-18-17”. The anti-dimming stick has had some exterior paint chipping, however the writing remains completely legible and still contains its original contents. The spare respirator tube is not in good condition and has suffered damage. The respirator/filter canister and its attached tube and gas mask are in a remarkably well-preserved condition. The respirator/filter still maintains most of its original yellow paint and has only seen some chipping. There is a paint-covered (presumably) manufacturer’s mark as well as “143H H” on either side of the connecting tube. The connecting tube has sustained no discernable wear. The gas mask itself is in a very well-preserved condition and has not suffered noticeable damage other than light wear over time, however the rubber has solidified and the mask is not flexible at all.
