My "Gruntz" Crusties from GZG needed a bit of heavy support. The problem is the heavy mecha from GZG looks a bit weedy to my eye - particularly the bottom half - see pic.
However some time ago I saw a pic posted on an internet board of a conversion using the torso, arms and legs of the GZG Mech with some donated legs from another model. I shamelessly pinched this idea, so without further time wasting here is my new Crusty Heavy Mech
EM-4 Miniatures plastic Mechs - £2.55 for 5! with the arms and torso from a GZG Crustie Mech. I'm rather pleased with it
