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.
Avner Strauss
During the years Strauss devoted many years to the research of catalogs and collecting whistles, he published hundreds of articles about the subject and about the History of whistle manufacturers in the 19th century and is considered one of the world's foremost authorities on the subject of collecting whistles, some of his articles and samples of his collection which might be the largest known, can be found on the Whistle Museum.
