This is a Forgeworld Sisters of Battle Exorcist from their Display Cabinets at GamesDay 2005.
When I was at Bristol Conflict, one of the nice things is the fact you can buy stuff which has not been released yet. One item caught my eye, which was the Sisters of Battle Exorcist.
Though I prefer the Forgeworld version, which looks more militaristic, the GW version has a certain charm and you certainly get a lot in the box.
The side panels are particularly nice and well sculptured.
