Standard Wire Gauge Chart - Historical Measurement Tool for Electrical Wiring #116748 (License: Personal Use)

This black-and-white illustration depicts a circular Standard Wire Gage, a mechanical measuring tool used primarily in the early-to-mid 20th century to determine wire gauge by fitting conductors into precisely sized notches. Each notch is labeled with an American Wire Gauge (AWG) number from 6 to 36, arranged clockwise around the perimeter, with a central blank circle for handling. The device features a small logo and bold text reading “STANDARD WIRE GAGE” below the center.
