The classic 'snail' whistle often seen hanging from the 1941 pattern Mae West or aircrew blouse. Chrome plated brass. Air Ministry King's crown markings and reference numbers '23/230' to one side with further reference numbers to the reverse '293/14/L1795'. Very minor loss of plating but in excellent used condition. Fitted with the original split ring. There are now numerous fake whistles on the market, some very convincing. We guarantee this to be an orginal period item and not one of these copies. Stock code MW18949.
