Early ignition coils!

I'm trying to find out how the early ignition coils look! The one to the left is dated week 25 of 1965 and the one to the right week 32 of 1973.

But check out the coil from my unrestored one owner Dart 65 with a datecoded coil frpm, week 40 of 1964. Totally different, both the text and the numbers!

How does your coils look on unrestored early A-body cars? Specially interested in late 1964 and ealry 1965 cars.
