Boatswain's whistle of the USSR Navy

Souvenir whistle boatswain's pipe with the symbol of the USSR Army "USSR Navy"made of stainless steel with the USSR award
The correct name is "Signal pipe", before the appearance of radio broadcasting on ships, it was an integral attribute of the main boatswains and drill foremen, as well as red Navy sailors dressed up as watchmen on the upper deck.
In the Soviet Navy, it was first introduced by the order of the Red Army of February 5, 1925, No. 39. There was no longer any mention of the pipe in the Uniform Regulations of 1934. Since the 1930s, it has become an element of the dress uniform of the parade units (the first rank).A great gift and souvenir for a lover of the history of his country.
