An iron alloy rod with an electrically-wired base. The base is 12cm long and equipped with three thumb nuts in different positions in addition to spiral-shaped electric wires. The reach of the base can be adjusted along the length with the turning of a screw. The instrument is largely made of copper and steel.
Primary Materials: Copper alloy, Iron alloy
Length = 50cm Width = 11cm Height – 12.5cm
Good. The surface of the object is corroded on the iron alloy surfaces. The coiled wires are particularly corroded and appeared covered in brown, degraded material.
