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 minor signs of crazing. The mask edges are 75% complete, the overall shape is very good and the rubber remains pliable bar some hardening at the edges. Air Ministry contract markings are evident on the facepiece moulding. The chamois inner edging is complete and really quite clean. The conical tube at the base of the facepiece remains in place and is also in good condition, complete with alloy pipe/valve within. The webbing harness is complete and retains some colour but no elasticity. The three press studs have varying amounts of their original finish. Fitted with a type 48 microphone assembly (type 26 mic 10A/12570 and short loom/plug) and anti-freeze inner gauze plate - all in very good condition. 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 very good used example of this type of mask. Stock code O22428.
