A top break revolver whose barrel and cylinder group hinge down at the standing breech, with a latch over the top strap and chequered walnut grips. Dimensions 0.057 x 0.156 x 0.195 m (X x Y x Z). Origin at the footprint centre, resting on y = 0; metre units, +Y up, muzzle and point toward +Z. Named pivots: hammer at (0, 0.1135, -0.0726); cylinder at (0, 0.1215, -0.0526). Connectors: muzzle muzzle at (0, 0.1215, 0.0974) facing +Z. The cylinder indexes on its own axis and the hammer thumbs back to full cock. The crane, the ejector star, the hand and the trigger linkage are modelled but static: they are a linkage, and a rigid node transform cannot drive one honestly. Rigid node-transform clips cock, spin drive named nodes on their own pivots. No skinning and no skeleton. Blued gunmetal, bright machined steel, dark anodised alloy, black and dark earth polymer, rubber, walnut, brass, copper, leather, olive paint, optical glass, concrete and emissive red, green and warm white for reticles, lasers, tritium and lamps. Physically based flat colours with no texture maps. Original invented design: no real make, model, manufacturer or marking is represented.
