DescriptionThe L.S. Starrett Co. Carpenter's Protractor from 1915 is a tool crafted from durable metal, reflecting the practical yet precise engineering typical of early 20th century American manufacturing. Its functional design features a flat, rectangular base (the straightedge) connected to a semicircular protractor plate via a central pivot. This pivot allows the arm to rotate freely for measuring or marking specific angles. The protractor plate is engraved with precise degree markings from 0 to 180, facilitating accurate angle measurement. Visible inscriptions include "L.S. Starrett Co.," the manufacturer, and the model "No. 189." Additionally, the words "Athol, Mass. USA" are present, linking the protractor to the nationally-known company's manufacturing origins in Athol, Massachusetts. The metal has developed a patina over time, showcasing subtle wear and oxidation. Carpenters in Albuquerque would have used tools like this in construction or design projects.On View
