An exceptional example of mid-20th-century naval navigation technology, this U.S. Navy Bureau of Ships Self-Synchronizing Alidade Pelorus Stand was manufactured by the renowned Sperry Gyroscope Company, Brooklyn, New York, a key supplier of precision instruments for the U.S. military. This instrument, Mark XXXI, Mod 0, Serial No. 320420, was built under Navy contract NXss 17019 and bears its original inspection tags, confirming it passed rigorous Navy testing before deployment. The pelorus stand is crafted in a striking combination of polished aluminum and solid brass, featuring a protective domed brass cover that reveals a beautifully preserved gyrocompass repeater dial.
