Before getting into these Italian hoplites-to-be I assembled three spear elements from Carthaginians. In some army matchups they can become Italians - but I didn't put any conversion work in, and they really do look like Carthaginians. I think they just end up giving me the later Carthaginians as a b option, the desperate "defend Africa" option which is not much fun.
These are all from the HaT Italian Allies box. I'll end up with three hoplite spear elements from minis like these, and a fourth hoplite spear element tbd. That will give me the 4x4Sp requirement for II/8b Campanians.
