Welcome to WebmasterWorld Guest from 22.214.171.124
The creator of THIS [images2.fotki.com] Gizmo has given it a specific name.
Your mission, if you choose to accept it, is to 1) provide the exact name, and 2) tell us its intended purpose.
I'm afraid clues will be few and far between since they might tend to lead you in the wrong direction rather than help you.
BTW, it is NOT a pipe of any sort.
my first guess was some kind of whistle (lower loeft part looks liek this ) but you said that it doesnt produce sound so that rules whislt out i guess.
