First an apology for misleading you - the fellow on the left isn't a head swap at all, he's just a Rebel Minis street punk (can't remember which pack he came from) that I though I may as well throw in with the other two.
The real subjects of this post are a pair of GZG armed colonists/civilans from SG15-V07 and SG15-V08. I've used a couple of the gas mask heads from SG15-XH2. Existing heads were carefully cut off and saved for re-use elsewhere. A hole was drilled down into the torso and the head clipped from its sprue leaving a 5mm stalk to drop into the hole. A blob of epoxy resin to seal it in place and it's all finished.
I'm particularly pleased with the way that the aiming figure has turned out. Rather sinister...
