Macedonians used leather helmets?

[Giannis K. Hoplite]

Noted something? Leather OR linen! Why do they say so? Because they are only ASSUMING where the attachments were from.No actual piece of leather or linen has been found in most of them. They said leather with bronze trim...is it possible they found only the bronze trim and they assume the rest was leather? In Vergina now the inscriprion under Philip's(whoever Philip that was) guilded armour,including some rings and such fittings, say "linothorax fittings" and I admit I don't think they have evidence for them being from a linothorax,but likewise many other finds that are inscribed as "leather armour fittings" are not justified either.
