The Real McCoy's Aviator Whistle

An essential piece of signalling equipment used throughout the forces in WW2, The Real McCoy's replica aviator whistle is made with solid brass and nickel plated for a silver-toned sheen. It’s equipped with a custom split ring— which would’ve traditionally been used to clip it to flight jackets— and engraved on both sides with subtle letter branding.Brass ConstructionNickel Plated Key RingEngraved BrandingMade in Japan
