Lufkin 873L Boxwood 24" Folding Ruler Brass Bound, Bubble/Glass Level & Protractor
The Lufkin No. 873L is a vintage, two-foot, four-fold combination tool made of warranted boxwood and brass. It is highly regarded by tool collectors for its "half-bound" design, which features brass binding on the outer edges for added durability and aesthetics.
Production Era: Lufkin began importing boxwood folding rules from Europe around 1915 until World War I, and they remained in production at least until World War II.
As a "combination" rule, the 873L integrates several distinct tools into one folding unit:
Folding Ruler: A 24-inch (2-foot) rule graduated in 1/16th inch increments.
Spirit Level: Includes a built-in bubble level for checking horizontal alignment.
Protractor/Inclinometer: Features an integrated angle gauge or protractor at the main hinge for measuring slopes and angles.
Half-Bound Construction: Unlike its "unbound" counterparts, the 873L has brass protection on the outer sides to prevent wear when the rule is closed.
