So, this is the one I acquired. It had 12 miles on it, and now it has 34319. If Ken says only 3 were made I'm inclined to believe him. I'm just guessing, of course, but it's not unheard of for parts to come off before a car gets crushed. The police speedometer story may be a red herring because of this. Again, I am just guessing.
The picture above was my picture, and I just took another pic to prove I still have it.
