ACME two-tone whistle AC144 []

When two cylindrical whistles are played, two notes are emitted at the same time, creating a comical sound similar to the whistle of a ship or locomotive. Once you play it, you will be captivated by its tone and may find yourself wanting to play it over and over again. Originally, it was blown by hotel doormen to hail taxis, but now it appears in wind band performances and is also used as sound effects in plays and plays. It is also ideal for use as a toy for children, play parties, school plays, and musical instruments for emotional education. ACME is a long-established British whistle manufacturer founded in 1870. The crew of the luxury liner Titanic also famously used ACME whistles.
