I have three whistles for sale:
Kerry Songbird High D: $95. Made in January '05. In perfect playing condition with a few of the usual surface scratches.
Granite Falls High D: $50. Made in October '05. Again, perfect playing condition, usual scratches. It seems to me that these whistles are modeled after the Kerry Songbird.
Hoover Brass A w/Blacktop: $50. I can’t quite remember how long I’ve had this one, but am sure it’s been over a year. Perfect condition. Requires a bit more air than usual.
All three play great but I have other whistles I prefer and these whistles would feel bad if someone didn’t play them. 
PM me if you’re interested or for pictures.

Heya Tiff! Didn’t think I’d see you here! What’s up with Mack’s A whistle? I don’t think I’ve seen you play it before at session or whatever. Have you called him to see if you could exchange for something you like better perhaps? He’s a great guy and will bend over backwards to help a whistler out. Give him a ring perhaps…

Brian, hi! No, there’s nothing wrong with Mack’s A. It has a great sound. Since I got my Overton A I don’t ever pick it up. Nope, never bring it so session cause we never play anything in A. You want it?

I sent you a PM, so please respond back as soon as possible.
The Kerry Songbird is sold.

The link above will take you to three pictures of the Hoover A and a sound clip, complete with numerous mistakes.
