By The Ohio Chemical Manufacturing Co. Dated 12-44. Size medium. The mask looks very good but the rubber facepiece has hardened in places. Overall shape is quite good but the right 'cheek' flap is not quite 'in line' and shows cracking internally if flexed. All strap components including the rubber parts are excellent, as is the original oxygen hose and end connector. Comes with the excellent original cardboard carton containing a spares envelope with instruction leaflet, press studs, webbing strap and oxygen mask clip/'flat hook'. A good display piece let down a little by the hardening of the facepiece. Stock code O18629.
