Description
This sundial consists of a thin rectangular brass plate. A hole at the top allows it to be hung. The brass gnomon blade has foliation along one edge. A tab-and-groove holds the gnomon to a brass fleur-de-lis which is screwed to the dial. A sun with an ornate "55" inside it is inscribed on the plate. The rays of the sun point to hour and half-hour marks (calibrated from 1 to 7 and 6 to 12 by 1) around three edges of the plate.
A mark at the top reads: 1732. A signature near the bottom reads: Karl Adzersen. The adjacent place name is illegible.
