A very nice and seemingly pretty scarce wartime Japanese civilian issue respirator complete with card carry case and instructions sheet. The respirator is in amazing condition, the rubber is soft and supple with no damage, the window is excellent as are the head straps, the filter is good and still retains its paper label around it. the internal card bung is in place (this would be removed before use) the original instructions sheet is with this and although tatty and dirty is good and strong. the card carry case is again excellent and retains its external paper label. The lid is good but shows edge tears and some loss of card in places.
