While I think that a sound clip doesn't fully convey the overall "feel" of a whistle, it's definitely a good start. So there you are a few clips.
The recordings below were kindly provided by Mr. John M. O'Hara. This is how my whistles sound when played (and recorded) by a competent whistler. Thanks a lot!
I wish I was as good a whistler as John... I hope you will not mind my playing technique. These sound clips were recorded using a simple microphone connected to my PC, and no audio effects were added:
