Whistlemakers - brass tubing for trade!

I have some brass tubing I’d like to trade. There are 30 pieces, each 4 feet in length. The wall thickness is 1mm, inside diameter is 13.9mm, on the outside is a factory applied lacquer. I acquired it at a time when I had delusions of making whistles myself. However, I am metal-working challenged, so I’d like to trade for whistles, or some other instrument I’m in the market for (bouzouki, octave mandolin, celtic harp, etc.) Contact me off-board via email if interested and we can work out the details, and answer any questions then. Thanks for looking.
