I have not used one (too small for my engine) but lots of tiny steam whistles with valve are for sale on ebay at a reasonable price.

I made a 2 inch siren for mine and it drives the local dogs mad but I can’t hear it!!. Some things just don’t scale.

The frequency of a whistle is controlled by its length and the shorter it is, the higher the pitch. Which is why little whistles annoy dogs and hurt the ears of small children. The diameter of the tube effects the loudness/volume of whistle.

I am in the process of designing/making a whistle for my engine and to get a deeper sound, contemplating a whistle with a dividing plate in the tube, making the sound cavity longer in a short tube. A bit like a chime whistle but with only one music note. ( I will post an update after it is made and tested)

What a neat idea! Let us know if it works. I suspect you'll need a pretty good joint twixt divider and tube
