World War I Replica Trench Whistle
Artillery shells and bullets whizzing over the trenches created a cacophony of noise. With all of this noise, shouted commands could go unheard. Trench whistles were used to overcome this. British forces were the first to make use of whistles in the trenches of World War I. The whistles were made by J. Hudson & Company, which was later bought out by ACME Whistles. They continue to manufacture whistles today.
