0962a - Dublin Model -M- Series Body Section only, for -Bb-, with one key

The price includes a fingering chart, thumb-rest  and a carrying pouch.

A key over the lowest tone-hole of the longer sized whistles allows small hands to easier reach the lowest tone-hole.  Many players do not need a key on a -Bb- whistle, but often need one or more keys on the much longer low-octave models.
