High C whistles in solid rosewood by Musique Morneaux 

Clean sounding 2-piece whistle/flageolet which is thereby tunable and easily cleaned.   Each one is in two pieces, the tenon also serving as the tuning slide; while meant for A=440, it can tune sharper or flatter to suit your needs as many trad sessions tend to be a little sharp while some religious bodies with their music programs and choirs at times tune a shade flat.

Price is for one whistle.
