Stores Ref. 22c/16. 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 good, flexible condition and complete with RCAF markings. Identical to those found with Air Ministry markings. Those pictured are notably cleaner than the ones we have left which are rather dirty / discoloured. Sold in pairs only. Stock code H19801.
