I've been pondering some things like you describe, too. This example has me scratching my head on possible arrangements that might be appropriate, though sadly The Met's write up and pictures don't give an entirely clear answer as to what's happening on the inside.Mac wrote: ↑Wed Dec 13, 2023 8:44 am
The holes over the ears as a persistent mystery. They are frequently found on helmets that are very wide, (there was a fashion for that) and my working assumption was that they were for ties to help stabilize and center the head in the helmet. They may well be for internal strapping to adjust the height of the lining, as you speculate. Whatever they did, it has not left much evidence for us.

Another thought I had was that the lower holes might facilitate a more easily removable lining. Wallace has some lining pictures with bra hooks at the lower edge that seem to substitute the typical stitching.
I found those online but haven't been able to get my drive to work on my new computer to get more information on if they are more modern additions. I have to admit that having bra hooks around the edge of my friend's helmet has a certain Weird Science appeal.
