I am selling a Chieftain A whistle, in aluminium, to which I added a tuning slide in aluminium. I bought it as a single piece, non-tunable whistle years back. It is in good condition and is a really good player. I selected it specially for its good tone.
Price £110 plus postage (£5 UK, £10 international).
A Chieftain whistle in the key of A sells new for £165.
I can also provide an additional body made by me in the key of Bb for an extra £30. Then you get an A/Bb set.
Please send me a PM if interested.
