Looks like a correct 1966 with correct type C bezel and very nice. Is there something about it that concerns you?
It might have been relumed. The big triangle is quite large on the right side. Better pics are necessary for assessment.
Not all had a pinhole, it seems later dials did not have them. The close up pic you’ve provided is a little blurry, but the dial in previous pic (non close up) looks good to me from what I can see
