Tin whistle
In recent years a number of instrument builders have started lines of "high-end," hand-made whistles, which can cost hundreds of dollars US each — expensive in comparison to cheap whistles, but nevertheless cheaper than most other instruments. These companies are typically either a single individual or a very small group of craftsmen who work closely together. The instruments are distinguished from the inexpensive whistles in that each whistle is individually manufactured and "voiced" by a skilled person rather than made in a factory.
J Hudson &amp; Co
In 1883 Hudson began tinkering in his toolshed to make gadgets to sell, including whistles. After observing local police struggling to communicate with rattles, he realised that his whistle could be used as a tool. As the story goes, Hudson, a violin player, accidentally dropped his violin and it shattered on the floor. Observing how the discordant sound of the breaking strings travelled, Hudson had the idea to put a pea in the whistle. This gave it an ear splitting rattle that could grab attention even a mile away. After a demonstration at Scotland Yard, Hudson had his first sale.
