Actually I beg to differ. I have it downloaded including the source files from when I first signed up as a citizen years ago. I’ll be happy to upload it via Google Drive if no one objects.
Edit: I had a closer look. Sadly I think at least half is missing. I recall being parts on texturing, rigging, and animating. However I’m pretty sure I’ve got all the modeling parts still. I might be able to find the full version in one of my very old backups, if it’s still around.
