Universal equinoctial ring dial for all latitudes. Standard dial (see related terms) except for the following details:-

The dial has a latitude scale, a scale for determining solar altitude, a date scale and a declination scale, but no zodiac scale. On both the obverse side and the inner rim of the equinoctial ring are hour scales and the equinoxes are marked at 9 ½ March and 12 ½ September. There is a star engraved on the slider rivet of the gnomon.

This dial is very simply engraved but contains very careful work with accurately divided scales. There are some minor bits of decoration, but generally the style demonstrates the austerity of English instruments at this time. It is signed 'Edm: Culpeper fecit' on the obverse side of the meridian ring.
