A whistle is an instrument which produces sound from a stream of gas, most commonly air. It may be mouth-operated, or powered by air pressure, steam, or other means.
Crafted from gleaming tin, this whistle is a streamlined tube with a blowhole at the narrow end. The cylindrical shape widens beyond the mouthpiece, concealing a hole for sound production. Its rounded opposite end features a loop for secure attachment to a string or chain, marrying simplicity with functionality in this silvery adventurer's companion.
