Made by Clarke Whistles, 2+ octave, 6 hole, conical rolled tinplate body (same as the Clarke whistles), but with a black plastic headjoint which was specially designed for these whistles by Michael Copeland of Copeland Whistles. Conical bore produces better sound: mellower, richer than straight bore.
The Sweetone Tinwhistle is the higher-end model of Clarke's plastic top whistles. It plays louder and clearer than the Meg whistle.
