Overview
This is a classic vintage No. 1206 aluminum folding zig-zag rule manufactured by the legendary Lufkin Rule Company. Unlike more common wooden folding rules, this aluminum version was built for durability and precision in demanding industrial environments. It features deeply etched, highly legible black markings and robust brass-plated spring joints that snap satisfyingly into place.
Story
In 1869, Edward Taylor Lufkin founded a board-rule business in Ohio to serve the booming timber trade. His company eventually moved to Michigan and revolutionized American industry by standardizing measuring tools. This aluminum ruler represents the peak of mid-century American manufacturing, built to survive a lifetime on a bustling factory floor.
Maker / Origin
The Lufkin Rule Company was a titan of American tool manufacturing, renowned for producing some of the highest quality measuring tapes and rules in the world. Originally serving the logging industry with specialized board rules, Lufkin expanded into steel tapes and folding rules, becoming synonymous with precision.
Condition & Value
The ruler shows light surface wear, minor oxidation, and some small spots of discoloration/rust near the first hinge, which is typical for a tool of this age. The etched lettering and numbering remain remarkably crisp, dark, and legible.
