I've seen pictures of a front cowl replacedment on an AD panel. In this case I think the cut was made in the windshield frame and everything in front was replaced.
It was Mark Woodsen's panel and the pictures were on his web site. I just don't recall the URL...
But my point is that TooMany is right, it could easily be a repair that mixed parts from different years, and that there is no dog to wake up!
