Speaking trumpets were used in the eighteenth and nineteenth century by sea captains and fire chiefs to amplify their voices. Large scale presentation presentation speaking trumpets were given to fire chiefs and sea captains to commemorate important events. Most of the ones known are made of brass or silver-plate. Very rarely they were made of coin silver, as is this one and a virtually identical one in the collection of the Smithsonian Museum of American History.
There is a marvelous painting on this web site showing in the upper right-hand corner one in use on a ship. https://ltwilliammowett.tumblr.com/post/659525998300348416/the-speaking-trumpet
