Thanks for your feedback. I also guess that the wholes are for holding fabric. Maybe a lining inside?
Is the missing passage from the ear flap to tha calotte normal (red ring on image 7)?

Yes image 1 looks like a terrible travesty but presumably the vendor had some evidence that it was at one time covered hence the modern fabric. The other images are Venetian sallets which illustrate better what I was thinking of. A covering with metal embellishments secured by staples , hence the pairs of holes in odd places.
