My latest items from eBay arrived yesterday. It's a GW Rough Rider model.  Here is GW's description and image of this model:
 
"Like Armoured Fist squads, Rough Rider squads are often attached to infantry companies to provide some fast moving support. They can carry a variety of weapons, but the most famous is without a doubt the explosive-tipped hunting lance." 

I spent the evening yesterday working on painting the model, but with a new theme other than the Attilan look. So I used all the pieces of the model except the torso/head piece. Instead, I used a spare IG Cadian torso from my bitz box. I also needed to come up with a solution for a left arm since the original torso/head also had the left arm connected. I decided to use a left arm from the Cadian Command Squad with the color flag.

After magnetizing the new arm, the next task was to find a base for the model. I only had a round slotted base, so that ended up being the only choice I had. I might need to find a rectangular base, since the small rounded base upsets the balance of the model.

Next, was the color scheme, and I decided on a red and bronze scheme for the rider, and a tan for the horse. Here is what I have so far:

I have not really decided on a head yet. The only ones that I currently have in my bitz collection are Cadian Infantry or tank troopers. I want something really different, so i might need to get online to try to find something that works with my cavalry non Attilan motif.
