Evidence for legionary vs auxiliary helmet patterns

[Peroni]

in response to Crispvs..

Idria and Verdun burials?

These were also found with conical round shield bosses and bent swords - the bosses are typical of flat auxiliary shields and the bending of swords tended to be a practise undertaken by provincial cultures rather than Roman IIRC, suggesting the burial was of a provincial auxiliary soldier.

Nijmegen shield boss..

and which is presently the sole piece of evidence which can be used to justify the use of curved shields by auxilia

No, we have a second find from Aalen. (see my write-up on curved shields on the website!)

Why is it that many iron helmets, when found, were devoid of their brass fittings. The so called Gallic H is one such helmet as is the so called Gallic C

The Gallic C was still left with its crest support!
