It does not look like much but there has been quite a bit of effort to get to this point. GW has some odd ideas sometimes. The Exorcist kit comes as an Immolator plus some special metal parts to convert to an Exorcist. But without instructions how to fit it together. So on to the GW site to see pictures of a completed Exorcist. Clearly if I had been less experience in modeling there could have been significant difficulties. Anyway here is where it is at at the moment:
The side panels where the doors were to be have been glued in place and baroqued into coherence with the GW supplied front and rear metal panels representing extra armour. The launchers have been partially assembled. Everything had been undercoated white and a base coat of TauSept Ochre applied. Bolts/rivets have been added to the surround for the door replacement panels through the simple expedient of cutting off rivets/bolts from spare IG tank metal work and gluing them on. Better than superglue rivets and easier than plasticard dowel..
