The Acme 535 Silent Whistle is the highest frequency whistle in the Acme range. Although not total silent the 535 is as close as you will get with an audible whistle. With the stylish design and the quality of the brass nickel plated materials the Acme 535 is the ultimate silent whistle. Complete with protective end cap with chain attachment.
