One of my favorite squads in the Warhammer 40K universe is the Inquisitorial Henchmen Warband. This motley crew of various characters really allows a miniature hobbyist to stretch the limits of his/her conversion capabilities. I have collected and converted, and am still in the process of collecting and converting, a number of miniatures that I use to represent the various individuals of an Inquisitor's Warband. Some of these are from Games Workshop and Forgeworld, while others are from various other table top game manufacturers or fabrications of my own created from bits and parts from both GW and non-GW kits.
With many of the models, I have maintained the “walking forward” theme I’m using for most of my Space Marines, which will make them go along nicely on the gaming table or whenever/wherever they are displayed together.
