Here are the Parthian cataphracts that my friend Joe painted for me. There are two group of twelve figures each from respectively A&A miniatures and Aventine miniatures. 
They are awesome figures and Joe did a great job painting them up for me. The A&A figures (the two groups in front) are a mix from their Parthian and Palmyran range of cataphracts. The Aventine figures (the two groups in back) are from their Parthian/early Sassanid range. I use them for eastern irregular cataphracts in a number of armies.
Here’s a close-up of the A&A figures:

and of the Aventine figures:

You can probably tell that the Aventine figures are a little more slender, but I don’t think it’s enough difference that you couldn’t mix them in the same unit. I just had all the A&A ones done before I got the Aventine ones, so they are separate.
I have another couple of 12 fig groups whose bases I haven’t yet finished. (Why do I need that many cataphracts???)
But because I have these I’ve got my older Old Glory cataphracts for sale Older cataphracts.
Joe also painted up some cataphract generals and they look nice on their round bases:


We put our generals on round bases for ADLG generals that aren’t included in units. It provides a distinctive easy-to-identify the generals bases.
