thanks for posting all the photos.
to err on the safe side I'm calling my data tag a reproduction until someone with more experience says it isn't.
For the last 20 years i've just owned '66 Shelby's, & None of Shelby's cars left his facility those years with a data tag on the door, so I don't have much recent experience with the tags.
Like I said, this car is an interesting mix of fine work on one hand, and almost deliberate sloppiness on the other. So nothing will surprise me.
