Stores reference 6D/473. This is the later variant of the E-mask complete with anti-suffocation/inspiratory valve and an elasticated webbing harness in place of the earlier leather types. The rubber is in very good condition with only very minor signs of crazing. The mask edges are 95% complete and the rubber remains quite pliable apart from some hardening and curling at the edges. Air Ministry contract markings are evident on the facepiece moulding. The chamois inner edging is complete although soiled. The overall shape is good but the conical tube c/w alloy pipe/valve is somewhat off-set through storage (this is a common occurrance and can be rectified with time). The webbing harness is complete though stretched/faded and lacking elasticity. All three press studs have most of their original finish. Fitted with the less common type 26 carbon microphone that has been cut from the original wiring loom. Please note that this mask is guaranteed to be 100% original and should not be confused with the 'hybrid' masks that have been offered elsewhere in recent years. Those have original metalwork and harnesses but brand new/reproduction rubber facepieces and linings. A good '+' used example of this type of mask. Stock code O22840.
