There is quite a debate about what is original going on in the comments under this Model A video-

Admittedly, the video is stupid. All it was supposed to do was show the car, never intended to see the light of day.
So, did we ever figure out what qualifies for "original"? Is this car what you would call "original"? Some commenters call it "restored". Where do you stand on this car?
