I have to face facts: I simply can no longer comfortably play my low whistles. Too hard on my wrists. So, I'm selling two excellent ones--made by Michael Burke--a low D and a low F. Both are in nearly perfect condition. They are about 8 years old, not sure exactly. The material is aluminum. The low F has an extra hole (a C hole), which comes in real handy though if you don't like it you can just cover it up easily enough.
If you're interested and want to see pictures, please private message me with your email address and I'll send them on.
Low F ~ $190 + shipping/insurance
Low D ~ $230 + shipping/insurance
