Hello fellow Ripper Historians . On a recent jaunt into Whitechapel I was fortunate enough to stumble upon this fine artifact , A friend of mine who has an antique stool in Spitalfields antique market had just that morning been given an old box listed as local artifacts , containing plates , cutlery and various other pieces . Sitting in the bottom was this old chestnut .. an 1888, 13 Bar street manufactured, metropolitan Police whistle . I was meeting Ed Stow in the Ten Bells , and after checking it out on line , he confirmed it as the real deal . Now I am not alleging that this whistle and its haunting tone , was at one time in hot pursuit of Jack the Ripper , but given its local provenance and its historically accurate date , I cannot tell you that it was not .
Well its not unusual for them not to have serial numbers. However it must be noted that 'The Metropolitan' whistle was not exclusive to the police. It was available commercially, with the most common purchasers being nightwatchmen.
That said, it looks of the era to me. The scalloped chain loop being a big pointer. Hudson operated at 13 Barr St between 1888 and 1909, and the writing stamp matches 1888-1899, though I've seen slightly different fonts.
