Iron, with a well-formed hemispherical bowl and recesses for the ears. At the rear of the helmet there are three embossed ridges and three semi-circular steps on the broad sloping neck guard.
The brow-band, of thin bronze sheet, is reeded and stamped with a pattern of laurel leaves and berries in pairs. This is soldered to an applied strip of iron.
The iron reinforcing peak if of right-angled cross section with an applied bronze strip on the down-turned flange. This is punched from the back of the plate with alternating bosses and circles of small dots.
The crown is crossed by two applied semi-circular cross-sectional strips of iron. One runs back to front and other side to side, the latter being riveted above the ear guards.
Soldered to the upper sections of these quaterings are crescent-shaped bronze sheet ornaments, with the points uppermost. The borders of these are decorated with punched dots and a circle of dots is also made in the broad centre of each one.
The cheek guards are almost flat, with raised central panels with semi-circular devices beneath the hinges.
