A scarce early American dry card seafaring compass by Robert Merrill of New York circa 1840. Round wooden compass housing with intact original card in very good overall condition. Gimbal-mounted within its original dovetailed wooden box. Lacking sliding lid. Compass face is 7" in diameter and the wooden box's size is 10" x 10" x 7". Outside of museum collections, very few of these compasses have survived from this early American whaling ship era.
