Vindonissa Gallic F Questions

[L_CORNELIUS_CETHEGUS]

This is a question for anyone who might be familiar with the Vindonissa Gallic F in the database. In the description, it states that there are five ridges in the occipital region. I count four but there are only a few shots to go by.

Also, I would assume there were originally two decorative rivets at each temple to hold the upper hinge to the cheek guard. There is only one remaining. Is that a safe assumption?

Thanks!
