A vintage industrial plumb bob constructed from solid metal with a tapered, teardrop-shaped body. The tool retains a significant portion of an original red painted finish over a dark metallic substrate. The body transitions to a faceted metal cap at the top, which holds a short length of white braided string. The base terminates in an integrated sharp metal tip designed for precision layout and vertical alignment tasks. A careful examination of the cap, body, and tip reveals no visible maker marks, brand names, or model numbers.
