Select fire machine pistol: a lengthened slide over a squared receiver with an extended magazine and a folding forward brace. Dimensions 0.04 by 0.20 by 0.29 m (X by Y by Z). Metre units, +Y up, +Z front; the origin sits on the ground at the footprint centre unless stated otherwise. Lime plaster, terracotta tile, grey limestone, oiled timber, blued iron, bright steel, teal-grey and sand-olive cloth. Rigid node-transform clips slide-open, slide-close, magazine-open, magazine-close drive the named parts on their own pivots. There is no skinning and no skeleton; every other surface is static. Original invented archetype: it carries no maker, model or product name, and no markings, logos or lettering. The bore is a modelled recess and fires nothing; there is no muzzle flash, projectile or damage data.
