      Morning hours appear on one crescent of this dial, afternoon hours on the other; the central bar indicates months. The crescent-shaped shadow-casting device, which projects from this bar, is missing. The angle of the upper piece can be adjusted to conform with any latitude shown on the small arced strip.
