Vintage Bosun's Whistle A.D. 1790 in box. Blows loudly. The box states that it is Admiralty Brass. The pipe part of the whistle looks like it's copper. The box has Amsterdam - New York on it and AUTHENTIC MODELS HOLLAND.
I'm not sure of the age. The paper insert looks like there's some age to it with the inside page having a waxy finish. The insert has the history and labels the parts of the whistle and how to hold it. The box style is a bit older with some wear and worn areas. 

Whistle is used and could use a polishing. 

Thank you.
