Water Crane

Standalone cast-iron water crane for a platform end or loco road: a fluted column about 4 m tall on a square base, a handwheel valve, a horizontal swinging arm with a hanging leather bag on an arm knob from stowed (parallel to the track) to over the track.

风格：low-poly, flat-shaded vertex colors, no textures, 2 materials: the shared opaque one plus a distinct surface (glass, water or chrome), which stays its own mesh through mergeAssets rather than merging into the rest; shares palette and scale with its kit
