Postmen’s whistles form a small but intriguing presence within the museum collection. The number of people alive today that recall their use in service may be dwindling, but they are a lasting and tangible artefact of a rural postal practice that has now ceased.

How would they have sounded? Well, we have a recording of a two chambered Metropolitan whistle, as issued to postmen, manufactured by J. Hudson.

The sound is a double note, delivered simultaneously. When tested by the Metropolitan Police in 1883, they reported that the whistle could be heard well up to 900 yards, indistinctly at 1000 yards.
