The Vintage 'The Metropolitan' Police Whistle, made in England I think between 1910 and 1922 (from having dated it against other models). Made by J Hudson and Company of Barr Street Birmingham and inscribed with Royal Irish Constabulary. This is a unique piece of police memorabilia that would appeal to collectors of police-themed items. This whistle comes with a chain, adding an extra touch of history and authenticity to its design. With its origins in Birmingham‘s jewellery Quarter and usage in Northern Ireland , this whistle represents a piece of British police history and would make a meaningful addition to any collection of police memorabilia or vintage whistles.
