Vertical disc dial, reverse by unknown zoom

Vertical disc dial, reverse

Vertical disc dial and perpetual calender for latitude 47 North. The dial consists of a circular brass disc with an altitude dial on one side and a sunrise/sunset calculator on the other. The perpetual almanac has three rotatable discs set on top of the main disc. The main disc has a date scale and the lowest rotatable disc features a lunar-age scale. Both can be employed for finding the hours of sunrise and sunset and the lengths of the day and night. On the middle rotatable disc there is one small pointer to mark the age of the moon. Beneath this is a hole through which the angular difference (given in hours and minutes) between the hour of the sun and that of the moon can be read from a scale on the first rotatable disc.
