Piano parts for art/sculpture (Mortimer & Coxwell)

I disassembled a piano to dispose of it. I saved the action so have a box of various parts in the movement. From the keys to the hammers. See the photo for examples. Lots more of each of these four kinds of parts. I've lready given a few away and will keep a few for my own use but the rest can go either all to one of you or some slection of the heap. Think creatively...
