This is Tobius Ragg, a Redemptionist pyromaniac recruited into Inquisitorial service. He's one of a selection of figures that I'm working on for my planned Inquisitor skirmish/adventure campaign.
I based this miniature on the Necromunda Cawdor ganger with grenade launcher. I've pinned the muzzle of a flamer from the Cadian infantry sprue onto the end of the launcher, & added Cadian flamer tanks to the model's back. They fitted nicely with the shoulder straps already sculpted on the figure. The fuel pipe is some wire sleeve from a pair of old headphones. The igniter flame is made from Green Stuff putty. I've aimed for a black leather look using 'Ardcoat varnish, whilst retaining some red in the overall scheme to suggest the Redemptionist cult. I'm fairly pleased with the light sourcing from the flame & the sooty effect on the flesh, but it's not perfect.
