GSW – William Dowler & Sons

William Dowler & Sons made whistles between the 1880s and 1904 but after 1904 they contracted manufacture to J. Hudson so their brand name continued for a while. This can help when it comes to identifying their whistles.

  • Whistle marked “Great Charles St” : 1880s-1901
  • Whistle marked “Graham Street Works”:
    • a tongue present in the mouth piece : 1901-1904
    • no tongue in the mouthpiece : 1904 onwards (manufactured by Hudson) [some whistles at this time were made by De Courcy but I haven’t seen any of these to know how to split them]
