Vintage the ECMA City Police Whistle – J. Hudson & Co

This vintage police whistle is well marked with 'the ECMA city whistle England' to the body, made from base metal with a white metal covering sadly it has had a lot of use and is worn down to the base metal in places. Interestingly Hudson & Co are very well known for the 'ACME' whistle and for some reason decided to reverse the name to 'ECMA' as shown on this example.
