As I said, there have been several people providing help on this project. One is Dan Tootill, who has been doing renderings and various research on this. I compared Dan's renderings to my 3D scans and adjusted mesh data which I used for creating the 3D models (overlays on top of the mesh).
Check out the renderings that Dan just sent to me. Dan and I have been on the same page about accuracy. We have been discussing what to do about the Commodore key. I think Dan's solution is pretty neat, but there will have to be a poll on what to do about this.
