I have a great three piece Delrin Rover with bag. This model is the “Rover” made of Delrin whith brass tuning slide and tenons, not the quieter “Phantom” model which is all Delrin. It is three years old. Please see the link below which says " wooden rover" , but refer to the Delrin model.

This whistle is a great session player with solid volume, great responsiveness, and beautiful craftsmanship. He sells them for $200 Canadian Dollars, €150, us $190,Or £126.
I am looking for a whistle for a trade, because I play in a small session and find that this whistle is too powerful.
