Looks like Leo has the guy pegged. I called him to let him know what he had. Needless to say he was a bit disappointed, but still swore it made turkey sounds. He put it up by the phone and turned the screw...it is indeed the friction from the threads that makes a bit of a turkey sound. Not a very good turkey sound, but it could be a turkey sound. He accepted the nutcracker finding, and after looking at some online I have to go with nutcracker as well. No doubt in my mind now.
Thanks again everybody,
Steve
