I have put two whistle sets on eBay. The first is a roasted birdseye C/D set. This is a beautiful wood, with grain that seems to change as you move it in the light. I am starting the auction at the regular price of a single whistle, because of a dark mark on the back of the C body, which can be seen in the last photo.

The other is a brass and Delrin C/D set with a body design borrowed from a famous make. I have just made a couple of these, to test the waters. I don’t have a name for it yet, so if you have a suggestion let me know. Maybe the O’Brien Traveller, or then again, I could name is after my daughter, Claire.
