I'm resurrecting my Scordsci unit suggestion and I am adding some extra images, accumulated over time.
For the lazy - this post features swords, spears, knives, a helmet and a couple of shield bosses, jewelry, belts, talismans, cavalry equipment, coins etc
Because horses are depicted on currency and there is a presence of cavalry equipment, I'd like to suggest that one of the units be a cavalry one.
Also, the short sword and sica makes me want to see a light-medium infantry unit - not necessarily a swordsman unit - there are many preserved spears.
