RCAF flying helmet cushions, black

RCAF stores reference 22c/16.  Original black coloured sponge rubber cushion inserts.  These were fitted inside the earpieces of B-types and other flying helmets with zipped earpieces.  They were intended to provide extra soundproofing and now have the additional benefit of improving the look of your helmet.  A little dusty/grubby but in very good, flexible condition.  RCAF markings inside.  Why buy reproductions on ebay at £35 a pair when you can have original issue?  Stock code H26868.
