Like most armies of the period, individual weapons and armour would vary depending upon the amount of influence form other regions as well as what was locally available.
The bust depicts a warrior wearing a silk or cotton shirt over which he has leather armour on which are rivetted metal plates. The same construction was used for the shoulder amour.
The metal helmet has three cloth neck guards, which have no metal plates.
The kit includes photos are of re-enactors, which show the wide variety of details.
The two photos of the painted bust are my rather mediocre attempt at painting, I am sure somebody with more skill could bring out more of the details.
