By The Ohio Chemical Manufacturing. Co. Dated 5-45. Size small. Box label is printed '8th A.F. Modification'. The mask looks good but the facepiece has hardened. The overal shape is reasonable but the right 'cheek' flap is not quite in line and shows cracking internally if flexed. The rubber parts of the harness are generally good and the orginal oxygen hose complete with end connector is excellent. As per details on the box this mask has had the rare 8th Air Force modification that involved adding rubber 'washers' over the oxygen inlet ports inside. Comes with the original carboard carton in good order. Inside this are the remains of the original cellophane wrapper, spares envelope, general instruction leaflet and instruction sheet for use and repair of the 8th Modified A-14 Cemented In Anti-Freeze insert and positive lock disconnect assembly. A good display piece let down by the hardening of the facepiece. Rare to find these marked with '8th Modifications' on the box. Stock code O18631.
