RAF Aircrew Whistle
Original WW2, RAF Aircrew 'ditching' whistle.
This classic 'snail' type whistle is often seen in wartime photo's hanging from the RAF Aircrew Battle Dress blouse.
Made from chrome plated brass and reference stamped either side.
Air Ministry kings crown markings on one side and stores reference numbers on the other.
This good 'used' example is in working order.
