Since you got these for free, and since they probably aren't going to amount to much in the playing department, I'd like to offer a trade. I'll make you a felted bonnet in exchange for them. I've been wanting a stand of 'pipes to hang on the wall, and these would do nicely. In the meantime, get yourself a prcatice chanter, find a teacher not far away, and start lessons. It's the most fun you can have.
