Up for sale is an Ian Lambe low-D whistle in excellent (as new) condition. For pictures of the whistle, see the maker's site:

The site lists the low-D at around $230 US. I will let this one go for $210 including shipping in the US.
The whistle is well in tune with itself, and has an especially easy and lovely second octave. Feel free to contact me via PM if you have any questions about the whistle.
