I know you can get keys retro-fitted on M & E flutes… so what about a susato whistle?
sweet beatutiful keys.
As far as I know the Susato keys are to make D easier to play with small hands, not for chromatics (but are available as retrofits). Keys for chromatics on a whistle seem at least theoretically possible, though.
Daniel Bingamon of Jubilee Music Company makes them.
