RCAF stores reference 22c/16. Original grey 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 H26870.
