Very small folding pocket sundial. The sundial is not complete but the compass is working. It is not surprising that some parts have disappeared over time considering the size of this sundial. It dates from around 1900 when only wealthy people could afford pocket watches and sundials were still common. For a complete wooden sundial see Quick Find 6706. Length 6.6 cm. Width 3.1 cm.
