An interesting whistle has cropped up on eBay. This acetate / celluloid (a type of plastic and often misidentified as Bakelite, though some books do call these whistles that) is marked "The Metropolitan" and has a maker monogram of J Hudson & Company. The original colour is a dark brown, then called 'walnut'.
Hudson's make thousands of the metal ARP whistles but in all the archives held at Kew I did not find mention of them producing a celluloid whistle (several other companies did) during the Second World War. This whistle was made in the 1930s and probably reused by a member of the ARP or Civil Defence Services.
The lanyard on the whistle does appear to be the style available during the war. An interesting and rare whistle.
