On second thought, the armors of the region have a very oriental look, so its unlikely that they will fit your setting... But Ill put the pics up anyway, who knows, might be useful for inspiration, at least. Here is the typical Indo-Persian armor, known as the Zirah Bakhtar or Jawshan:
This armor would have been worn with a helmet and some bracers:
Another type of armor was the Char Aina, which was basically four plates worn over mail:
Early Russian weapons and armor were closely inspired by the orient. Here is an east european Bechter:
To me, the above armor has the most Roman look of all of them.
The Sindh region (where Im from) is quite unique in Indo-Persia in terms of armour because it was the only place where something that could roughly be considered plate armour was used. It was basically interlocking plates linked by chain. Some pics of Sindhi armour:
The problem with most of these images is mail armor looks quite awful when it is hanging on sticks, as opposed to properly fitted on a warrior.
Alternative to mail, leather armour, called chihalta hazar masha or coat of a thousand nails was used:
