The form of the 'eybrows' appears almost unique to this helmet; there are three embossed ridges, but there is also a fourth ridge (consisting of two embossed lines) that sweeps backwards over the crest of the helmet bowl, between the 'eyebrows'. There is a smiliar feature on the helmet from the Guttmann collection, although here it starts higher up the forehead and is not positioned between the 'eyebrows'.
The base of the helmet appears to be decorated with a series of embossed figures that closely resemble the 'ovolo' patterns found on certain types of samian pottery.
The helmet carries a series of decorative rivet heads in the form of shallow cups, that may once have held enamel. There are theee above the brow, two more in the centre of the forehead (arranged vertically), three on the neck guard and a further two, one at the bottom of each cheek guard. The Imperial Gallic 'G' helm (private collection, presently on show at Carnuntum Museum) shows these decorative rivet heads, but in that case the enamel has survived.
Each cheek guard hinge is secured to the helmet bowl by two rivets. Unusually, the cheek guard hinge is not riveted to the guard itself, but is an integral part of the hinge mechanism. Apart from the above-mentioned decorative rivet head, the cheek guards are devoid of decorative features.
