The largest difference I have found is that the assembly line installed cap have a cone shape to the VERY center on the outside, the caps made for the next run have a rounded dome and the edges are not as sharp.
If you close your eyes and run your finger lightly over the center of the cap you can feel the actual point on the cone, this has been checked on many original cars by myself and or other collectors with survivors and known history.
The first two are the rounded dome shape... the last two have a cone shape - NOTE the reflection in the center and the straight lines versus the curved shape of the reflection in the first two.
I have found that most parts which were subjected to second runs had the parts manufactured from original samples which were polished thus knocking off the sharper edged and lessening the details. the CONE shape makes perfect sense as the original pattern was most likely cut on a lathe.
