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.
W Dowler &amp; Sons
The Dowler family was engaged in the brass founding business since the late-18th century and had been making whistles since the early 1860s at least. In 1876, the company was named after William Dowler, following protracted legal fights concerning inheritance between the brothers George and William Dowler.
