Just shipped off a bunch of 6mm scaled upgrade bits for the tank I've designed for Vanguard Miniatures
From left to right: Front hull iconography plate, twin linked HMG, twin linked flamethrowers, twin linked subatomic heat weapons. Basically your three different types of Immolation tanks for the religious sisterhood. But could probably also be used for more inquisitorial themed armies.
From left to right: left missile pod, right missile pod, missile launcher turret, heavy laser cannon, light battle cannon, quad autocannons, medical transport front hull icon. I decided to ditch the roof part of the medical transport for multiple reasons: (a) it was too thin to cast at this time (b) doing it true justice would mean re-designing a hull a bit (c) economic reasons. Note that the medical transport is most likely an objective, so going all crazy on it regarding design work and printing/casting simply isn't worth the money.
Extra armour for the IVR tank, either plating or reactive armour.
