Technical Observations: The surface is metallic with some brown and green. The tripod stand appears to be a modern fabrication, as there is little evidence indicating antiquity. Modern tool marks from drawing the rods and wires, filing, and soldering are visible on the surfaces. Holes on the top of each leg are irregularly shaped but show turn lines inside. An isolated area on the underside of one of the top wires has pitting and some corrosion products inside, but even these could be modern.
