I am bumping this old thread up so that others can read it.
I especially appreciate and enjoyed reading what Randy T wrote in post #35, on page #2. Words of great wisdom and insight from decades of experience handling and inspecting more helmets in his lifetime than most of us can imagine or ever hope to handle in-person.
I wish we could see the photos of the original helmet that started this thread. I understand that the original owner of the helmet requested that the photos be deleted. Regardless of this, there are other useful photos of other helmets and eagles that were posted, along with comments about these other helmets.
Best Wishes,
Alan
