The Lensatic Compass became the standard issue compass during World War II. As the successor to the M-1938 Prismatic Compass, the Lensatic Compass was simpler and cheaper to manufacture. This Stanley London solid brass reproduction of a Military Lensatic Compass easily folds to fit in your pocket. The compass card has both the standard 0 - 360 degree scale, as well as the 0 - 64 Mil scale (one yard at 1,000 yards). The cardinal points are luminous for easy glow-in-the-dark viewing. This brass pocket compass features a standard glass bezel with two lines at 45 degree angles. The bezel also rotates with detents so you can change the heading reference a known amount without looking at the lensatic compass. The front sight has a magnifier to simultaneously view the magnetic heading when taking a sight. Folding the sight down operates a needle lift mechanism to protect the compass bearing. On the side of the brass compass housing is a needle freeze mechanism to hold a reading. The brass pocket compass measures 2 1/8 inches (5.4 cm) in diameter, 7/8 inches (2.2 cm) thick, and weighs 4.9 ounces (139 grams). This compass is beautifully crafted from solid brass and has a rich antique patina. Your personalized compass inscription can be engraved on the front or back of the brass lensatic compass.
