Need help indentifying a boatswain's whistle US Navy

Hey Guys,

I have a boatswain's whistle from a friend of my dad's who was a WWII vet. Could someone help identify this? It say's penn mint on the top. No other markings that I can see. It's attached to a braided cord. Any info you could provide would be much appreciated. It appears to be silver. My biggest question is if this is a US Navy issue item, or aftermarket?

Thanks!

It looks correct. They can be had easily through various sources but the real ones are solid and well made.

Thank you sir !

I'm sure there's other guys here to tell you details but they haven't seen this yet. Give them time...

It's called a Boatswain's Pipe.

In my WWII Navy days it was usually referred to as a "Bo'sun's CALL also.
My lanyard did not have a metal hook. It looks like mine, except my lanyard is white,
FWIW

I think RN models had a wide broad arrow marking too.
