Compass dial, reverse
Compass dial for latitude 50 north. This is a round brass fob sundial with a suspension ring for attachment to a fob chain. The dial-plate (which is off-centre) is supported by two crossed radial gilt-copper struts, with an open ring at one end. The plate is printed paper with an hour scale numbered clockwise 6-12, 1-6 and has hour-lines that radiate from the base of the style. The gnomon is shaped and made of copper. The compass is of printed card. It has eight points marked by French initials and North is further indicated by a fleur-de-lys. There is a magnetic variation scale, divided anticlockwise -30, and a double-headed arrow marks the magnetic variation at 21 West of North. The needle is blued at its North end. On the reverse side, the equation of time is laid out in concentric circles; it is covered by convex glass.
