Tarentine Light Cavalry
These are RAFM riders on various old horses, including Minifigs, Ral Partha, and Garrison..sorry the RAFM horses generally (suck) aren't too well done.
Tarentines were quite the rage at the time as they not only were excellent javelin skirmishers, but they also used shields...which soon led to alot of Successor cavalry dropping their long spears and opting for the extra protection of shields also!
The officer below sports a Dark Age Design laurel leaf transfer from their Hoplite shields range which I felt appropriate!
