Composite (?) attic helmets with scales and hair locks

[Idomeneas]

Greetings



There is a particular kind of probably attic/chalkidean helmet that we find drawn on pottery during the early-mid classical era. Sometimes it appears to be a hybridic corinthian with ear cuts, sometimes it appears to be more open faced. Sometimes it doesnt even have a nose guard, but almost always there are indications of hinged cheek guards. It seems to have replaced the archaic type corinthian helmet in the depictions of gods and heroes. Most of the times it appears heavily decorated with scales, nails, or checkered painting. Some of these seem to have eyrbrows and above the representation of forehead hair locks (bangs?), in the popular archaic/early classical style.



A characteristic example can be seen in this Brygos painter work.




The helmet of Achilles has a checkered pattern and these forehead locks. Judging from the lavish artifacts in the scene, we can assume that these kind of helmets were considered as top notch.

Here is another example depicting Achilles dressing Patroclous wounds



The hair locks are missing but the whole helmet is covered in scales.

Ηere is an example with both hair locks and scales



And here is a modern reconstruction

These helmets appear very frequent in pottery but to my knowledge we have not recovered any. My main question is, were these some kind of hybrid, composite helmets or they were just highly finished attic/chalkidean helmets? The scale pattern appear even on some corinthian helmet drawings. Were these real scales or just a sculpted/painted on decoration? The same for the hair locks. Were these sculpted in bronze? Were they a separate piece possibly covering joints? Could they be made out of a different material like the reconstructed one?
I have seen an example of italian attic helmet with extruded hair locks, so Im not so sure thet they would be made from a different material even if it was an extra piece.

Your thoughts on the matter will be appreciated.

Thanks
