Acme Siren England Brass Whistle

Bought this at an estate sale. What kind of whistle is it? I thought maybe one of those steam whistles with all the holes in the top. 2 3/4" long.

 

OOOOOH....I've got a similar one....it's a 'siren' whistle as well.....hope someone answers it for you.....then we'll BOTH know!!!! Don't remember when/where I got mine, but think it's also English....now I'll have to go check!!! Mine is NOT is old as yours, I'd say! And not brass like yours, but otherwise, the SAME....3 inches long....stainless???

 

Thanks Aquitaine and Dave

Bob Dylan used it.
Uriah Heep used a tea kettle on The Wizard...

 

The Coyote would use this to try and catch the Roadrunner. He was always ordering gadgets from ACME!
