YOU WILL RECEIVE ONE (1) LONDON POLICE WHISTLE WITH ORANGE NYLON LANYARD SHIPPED BY USPS..... ONE OF THE EARLIEST USERS OF THE POLICE WHISTLES WERE URBAN POLICE FORCES, WHO USED THEM TO ALERT NEARBY OFFICERS OF A NEED FOR REINFORCEMENT; SINCE POLICE BEATS WERE DESIGNED TO OVERLAP, A LOUD WHISTLE WOULD USUALLY CARRY FAR ENOUGH TO BRING SEVERAL OTHER OFFICERS TO ASSIST. THE RISE OF THE AUTOMOBILE IN THE EARLY 1900S QUICKLY MADE WHISTLES LARGELY INEFFECTIVE, AS THEY COULD NOT BE HEARD OVER THE DELUGE OF URBAN TRAFFIC, AND THEY WERE QUICKLY ABANDONED, ONCE THE FIRST TWO-WAY RADIOS WERE BROUGHT INTO SERVICE. THE WHISTLE IS RETAINED BY SOME POLICE FORCES TODAY AS A SIGNALLING DEVICE, GENERALLY, BY URBAN TRAFFIC CONTROL OFFICERS IN AREAS WITH HEAVY PEDESTRIAN, BICYCLE AND MOPED TRAFFIC. ENGRAVED CEREMONIAL POLICE WHISTLES ARE SOMETIMES PRESENTED TO POLICE OFFICERS UPON OCCASIONS SUCH AS THEIR RETIREMENT. if you want a classic wilver whistle, like the coach or lifeguard uses, i carry this item, go to my other items and search keyword WHISTLE BID AND BUY HERE IN IN ABSOLUTE CONFIDENCE SINCE I HAVE THOUSANDS OF POSITIVE FEEDBACK AND TEN+ YEARS EXPERIENCE.
