Thanks. I'll see what I can dig up on those battles. Xenophon's Hellenika didn't seem to have much, but perhaps his Cavalry General text may include prescriptions for equipment (though prescriptions weren't the same as practice). The main puzzle I tried to crack were what the cavalry of Spartan king Agesilaus II may have looked like circa his Asian campaign and Koroneia 394BC. He did raise Asian Greek cavalry from Ephesus, gained and lost Paphlagonians, but managed to beat the Thessalian cavalry who were some of the best in the region. Sadly, I can't find details on what basis they beat the Thessalians. Anyway, where history doesn't provide an answer wargamers have to just make an educated guess. My way forward at present is to assume a motley collection of Ionian cavalry that could include Greek-style as well as Asian-style mercenaries.
