Early Scaling Rule
A scarce, early scaling rule in original as-descended condition.
Made from a single body of maple wood with a faceted 8-sided body, chamfered by hand, likely with a draw shave. A pewter cap is attached at one end.
A large series of lines are formed on the body using a marking gauge. Each number throughout is carved by hand marking each measurement.
Scaling rules have been used historically for measuring widths of logs to determine square edged boards to be extracted.
Remains in overall excellent condition given age and use with superb surface qualities. New York origin. Ca. 1800-1825. 24"L.
