This is from my working piano, the speakers went bad and I was going to convert it to a portable midi controller but found a great deal on an original Midiboard and just put this in the garage but now I need the space. Stripped it down yesterday and took the photos last night. Could be a real piece for your project. I love the Kurzweil wooden keys, way better than any plastic keys in my price range.
Here are all the photos.
