The 18th C. Sundial and Compass number CO012 by Authentic Models is a part of the Compasses Collection and measures 1H x 3.3 inches in diameter and weights 0.75 lbs. and is packaged in gift box, upc. Not that long ago people actually lived by sundial time. Every village and town functioned on local time, depending on local latitude. The arrival of trains and mail coach traffic created a need for coordinated time. Our travel sundial needs a compass to find north. Raising the triangular gnomon upright while pointing the compass needle North will show the time. The correct time will show only if the local latitude corresponds to angle of gnomon. Bronze dry compass, hand colored reproduction compass cards. Hand aged and hand polished.
