In February of 2015, I got one of my current set of actively used whistles. It’s a Sweetheart blackwood whistle, purchased at Dusty Strings, and it has a wonderful voice to it. I still use it in sessions.
I originally posted about this on angelahighland.com, with a mirror post on Dreamwidth. And here are pics of it!

Whistle in the bag
This is the bag that came with the whistle--two sections in it for the whistle pieces themselves, and another section to contain the brush and the cork grease that came with it too. Because this is a NICE whistle and will want proper maintenance!

And here's what the whistle actually looks like, before it's put together.
