Need Pictures of Accurate Brass Coolus Helmets

[Pointer]

I am looking for pictures of historically accurate Coolus Helmets with the spike type crest mounts.

I am not sure of the letter such as "C" "E" "G" or others.
Your wisdom, pictures and help will be appreciated.

I saw one the other day that did not have rivets for the cheek plate hinges, nor did it have Feather Tubes.
It also appeared to have very thin metal for the cheek plates and the Neck guard.

Any and all information?

Thanks Patrick.

Drawings could be of some help as well. Thanks

Where you mention that the cheek plates and neck gaurd were of thin metal it is from the fact that many Coolus helmets were hand beaten out from thin sheet metal.
