During World War I officers would blow a whistle and thousands of men would stream out of an attacking trench and run across No Man's Land into a hail of machine gun bullets and artillery fire from the enemy.
This copy whistle is dated 1916, the year of the ill fated Somme campaign. It has an arrow stamped on it which was used to show the whistles were the property of the British Empire.
This is a reproduction of a World War I trench whistle made from metal with the date 1916 stamped on it. The whistle is supplied in a clear bag with a header card explaining when it was used.
