OK, I do have lots of cataphracts already, but none which were overtly Sassanid - so a blister pack of a dozen seemed like a good chance to add 3 units to my mostly Legio Heroica ADLG army, and to get some size comparison photos of the W&E cavalry as well.
Here are the full dozen from the blister pack. The pack has (well, mine did have) more riders than horses, with a few officers and standard bearers to include if you want - which of course I chose to do.
Cataphracts are a decent host for a Sub General in ADLG, so the standard and sword-waving chaps in the middle may well be an embedded Sub General with some regularity.
Here are 8 of the W&E guys, with a textbook Essex cataphract unit in the middle of the line.
The proportions are a tad different, with the Essex ones looking bulkier and having stumpier horses but bigger bodies for the men, but they are basically the same height at the end of the day.
This shot has the Legio Heroica Sassanid Asarvan cavalry in the line. Again, not a great match in terms of stature but a decent one in terms of overall height.
The W&E Cataphracts are from their first range of releases, which seem to have fairly slight and short cavalry riders so perhaps later ranges will be a bit chunkier.
Here's the General and standard bearer. I wanted a fairly colourful mix of figures with different types of barding to match the look and feel of my existing Asarvan.
From the rear you can also see they have a fair selection of cloaks, allowing a more irregular look as well.
