I have two soprano d whistles made of African blackwood by David Boisvert. www.greewoodpipes.com They have brass ferrules and tuning slide. They have excelent tone and play great. I am only selling one, and you may pick which one you would buy. You may see a review of a greenwood at www.tinwhistler.com
The new one is $200. and is in new condition, and the pre owned one is $150. with two scratches if you look for them. Plus $5.00 for shipping to the lower 48.
The pre owned has been sold. There was a lot interst in this whistle. David makes whistles without any chiff.
