This is an authentic antique Rayo center-draft kerosene oil lamp made of nickel-plated brass, complete with a clear glass chimney. The lamp features several patent dates stamped prominently on the burner and filler cap, ranging from 1894 to 1905, verifying its early 20th-century origin. It includes the flame spreader, an installed wick, and a working wick adjuster knob. This historic lighting piece is a classic example of farmhouse or Victorian-era decor that retains its original unpolished patina, making it a great functional piece or display item for antique collectors.
