History. The Dowler family was engaged in the brass founding business since the late-18th century and had been making whistles since the early 20022s at least. In 1876, the company was named after William Dowler, following protracted legal fights concerning inheritance between the brothers George and William Dowler. In 1870, a large fire that started at the vesta match-making department destroyed the factory, halting production for over half  a year. The tragedy was well-covered by the newspapers at the time, as Dowler was one of only 20 Birmingham companies employing more than 500 workers. The company was located at 91 Great Charles Street and later Graham Street Works (beginning in 1897). The button factory exists to this day as W Dowler & Sons Ltd. 11-15 Brearley Street, Birmingham 19. Whistles. Dowler was one of four large British whistle makers in the nineteenth century along with T Yates, James Dixon & Sons and J Stevens & Son, later joined by J Hudson & Co. Models and types. 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. The company subcontracted manufacturing to A De Courcy & J Hudson & Co. from about 1904 onwards. Body Stamps. Dowler was the largest supplier of Beaufort  whistles to particular police forces during the 1870s. From 1884 onward, GSWs became the main standard with most police forces after J. Hudson & Co. won the contract for supplying the Metropolitan Police in 1883. With rare exceptions, 19th century stamps bearing a specific Police Force name were either made by Hudson or Dowler (Dowler being much more scarce). Police Forces stamps either on Beaufort or GSWs whistles made by Dowler include Other Stamps on GSWs: The First Dated Army whistle (1894) appears on a Dowler GSW.
