The Inquisition has been a core interest of this blog. The imminent
release of the new digital codex has reignited interest in the older Inquisitor minis here. This below is a favourite. It dates back to 2006. It is a simple conversion from and Imperial Guard Techpriest Enginseer and the converted weapon - a combination of a grenade launcher and Tau skimmer strut - if recollection is accurate, is intended to represent a psycannon as there were no parts for one then. Now with some spares from the Grey Knights and the new codex coming out its probably time to revisit this mini.
The archaic looking power armour along with the hooded and masked head seems to fit in with the Inquisitorial theme to allow a convincing conversion.
