The top is a thick dark blue circular ring; below it a central metal column with a copper-toned sleeve and silver-gray metal tube; the base is a royal-blue circular platform. Three slender silver-gray metal legs angle outward from the base, ending in black round feet. A knurled brass-colored cylindrical knob or connector extends from the left side of the base, and a silver metal corrugated hose fitting extends from the right side. Metal and engineering plastic materials, slight reflections and minor wear, soft even studio lighting, subtle shadow, slightly high front view, aspect ratio about 3:5.
