Just picked myself up the Ammo droid from the Battlefront Droid Figure set.
I had to get it as it goes really nicely with my other Gonk droids and R2 collection that I am building.
Essentially this is just a repaint of the Saga Gonk droid, but without the had thing, or the cables around it's middle. It's a really cheap figure as they have not even bother to fill in the holes were the cable would plug in. But as I got it for 99p I'm not disappointed.
