The classic 'snail' whistle seen hanging from the 1941 pattern Mae West or aircrew blouse in many period photographs. 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'. Minor loss of plating but in very good 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 original period item and not one of those copies. Stock code MW26581.
