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
Dowler made several kinds of whistles, notably Beauforts & Cased Beauforts, as well as general service whistles (GSWs) and Porteous top GSWs. Dowler also made button whistles: escargot-type whistle with metal buttons or coins at the sides of the barrel. Though Dowler is mostly known such models, rare models attributed to him include the Hiat Registered Design of 1894: a combination of an escargot whistle with button sides and a beaufort with mouthpiece, sometimes referred to as Crest-top Beaufort.
