This 1 of only 2 complete examples of this kind, known to be found in the last 20 years. A true museum piece. This ingenious sun dial is self-aligning! The gnomon is attached to the compass card, so one just holds it level, waits for it to settle, and reads the sun time from the shadow! Material: Brass Size: 1 1/2" diameter Crystal: Original Glass dome Needle: Dry card Graduations: Cardinal & inter-cardinal points Weight: 1/2 oz. Stop: None Markings: Magnetic Time Keeper & Compass (on lid) D. L. Smith's Patent August 23, 1870 (on base) Manufacturer: Unknown Included will be a printed copy of the original instructions for this item, truely fascinating. The lid, with its shining sun in relief, is in fine shape, not dented or dinged and showing a nice warm patina with the beginnings of light verdisgris over perhaps a third of its surface. The lid presses on smoothly and securely to the base, which also has a warm tone throughout and is free of any damage. The brass gnomon is securely in place. The compass card revolves smoothly and seeks north well.
