The Italic crest support holder is a raised disc with a slot, rather than the Gallic flat rectangular tube. The brow reinforce, not present on some Montefortino types, is either flat or has a turned-down edge. There is usually a crest knob, made in one piece with the skull on a Montefortino, but soldered or riveted onto a Coolus, and there may be feather tubes at the temples. Chinstrap rings are identical to Imperial helmets, although earlier examples have studs outside the cheekpieces instead. Bronze helmets may be entirely tinned or silvered.
Some examples are silver with red enameled centers.
Earguards, whether of brass or iron, should at least appear to be made in one piece, even if welded or soldered. Coolus-type crest knobs may be turned or cast, while Imperial crest holders are made of sheet brass. Brass hooks or rings for securing the crest are also present on most Imperial-style helmets. Anneal well and bend to fit, re-heating if necessary to avoid bad puckers. Then slit the tube open around the inside with a dremel tool and fit it into place, and hammer carefully to flatten it.
