BUZZ RICKSON'S BRASS WHISTLE Survival whistle, standard equipment for Air Force pilots. It is an indispensable piece of equipment for pilots, such as a distress signal, and is an accessory that matches the A-2 and cotton flight jackets. This whistle is made by special order from ACME, a trusted manufacturer synonymous with whistles founded by J. Hudson in 1870. The high quality is backed by a long tradition. It is a famous episode that the crew of the luxury liner Titanic, which sank in 1912, also used ACME whistles. Today, ACME is a brand with a high international reputation, used by referees in a wide range of sports such as the Olympics, FIFA World Cup, UEFA Champions League, and NFL. You can also expect the brass to change its color over time to a more sophisticated texture.
