This brass boatswain's call is a handheld, manual whistle for maritime signaling. This traditional type of instrument is used for acoustic signals on board and requires neither an electrical connection nor fixed mounting.
The whistle is operated by blowing into it. The signal can be varied by controlling the airflow and partially covering the aperture, allowing for different signal patterns to be produced. Boatswain's calls are traditionally used for command and salute signals on board, among other things.
The construction is made of brass, and the product has a documented length of 14 cm. There is no documented specific surface coating, volume, tone frequency, or signal approval for this model.
