Polyhedral dial for latitudes 23°-77° North (base latitude 48° North). This wooden cube dial is set on a wooden base-plate supported by four feet. Both the obverse side of the base and five sides of the cube are faced with printed and coloured paper. A compass is set into the base. The cardinal points are named in French and the magnetic variation is marked at 18° West of North. The underside of the base has a table of latitudes in two columns for places in Europe, primarily in Germany. A turned wooden pillar, with a pivot joint half way up, supports the cube. There is a horizontal dial and a vertical dial on each face of the cube. Both the West and East vertical dials have a diagonal hour scale with parallel hour-lines and a declination scale. There is a metal loop at the top of the East face to which is attached a string plumb line and lead bob, which act as a latitude indicator. Three shaped brass polar gnomons are set on the horizontal, North and South dials. The gnomons for the East and West dials are two pins (possibly replacements).

The towns listed on the base of this dial show that it was intended for use mainly in Germany. It was probably made in Nuremberg, whose latitude is close to the base latitude of the instrument. Printed on the North face is the signature of 'E. C. Stockert'.
