The Acme Whistles TH147NP Siren Whistle is sometimes referred to as the cyclist's road clearer. This unmistakable whistle sound—from a design introduced in 1895 and patented in the same year—still finds numerous uses. From tribal dances to marine signaling, this complex whistle is made with a watchmaker's precision.

Comments about Acme Whistles TH147NP Siren Whistle:
I love the sound of this whistle! I'm using it in a play that calls for the character, based on Harpo Marx, to whistle his replies...since I can't whistle, this is perfect!! Thanks for bringing a "voice" to the silent Marx Brother!!
