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'. Slight loss of plating but in excellent overall used condition. There are now numerous fakes on the market, some very convincing. We guarantee this to be an orginal period item and not one of these copies. This one reputedly belonged to Phillip Potts who was shot down 18/8/44 becoming a PoW. Stock code U21330A.
