Two leaves of bronze 1mm thick, model two hulls, as a reversed boat with a keel. This kind of valheg helmet (not complete here), or barfle, see cimier, crest; & some with stag, reindeer, etc, adorments, is dated from -1100 BC to -900 BC.

Each helmet is always different in its décoration, shape and size, following the artisan artist who mades it. We find it everywhere in Iapitea (Eurasia) from Gallia as far as Siberia.
