WW1 British RN Navy Brass and Copper Bosuns Whistle

The WW1 British Royal Navy Bosun’s Whistle, also known as a boatswain’s call, is a signaling device traditionally used by naval boatswains to issue commands on board ship. This example is constructed from brass and copper, measuring approximately 4.5 inches in length. The whistle features a curved shank and rounded buoy, consistent with designs used by the Royal Navy during the First World War. The combination of brass and copper materials not only provides durability but also resistance to the corrosive effects of a marine environment. These whistles were used to convey instructions, particularly in situations where voice commands could not be heard over shipboard noise. The design remained largely unchanged throughout the early 20th century, with later variations produced for ceremonial and commemorative use. This item offers a tangible connection to the daily routines and discipline of British naval life during the WW1 period.
