H.R.Robinson Helmet Typology

[Peroni]

I would agree that the Heddernheim is very much a type of its own as are many infantry and cavalry types.

Perhaps level 2 should be not whether the helmet is infantry or cavalry, (for the most part this is reasonably obvious from the form of the helmet itself) but whether it is of Montefortino, Coolus, Weisenau, Ribchester Heddernheim etc etc ad nausium.

That's a good point to start, as it gives a framework for us to proceed. As you say, the question is which groups to include at Level III!

Perhaps crest fitting, occipitals eyebrow decoration? again the list is potentially very long!

But, removing the level 2 infantry/cavalry allows for the level 3 to be more concise without introducing a level 4 or 5 in most cases.

Most* helmets will fall into categories 1 - 4 at most without need of 5 unless there are specific differences (i.e. the Gallic F with the repaired crest fitting of Italic form from Sisak)
