Universal equinoctial ring dial for latitudes 0°-90° North. Standard dial (see related terms) except for the following details:-

The dial is for northern latitudes only and the bridge and suspension ring are missing. A bracket is riveted to the ring, which slides in the grooved rim of the meridian ring. The latitude scale is divided clockwise [0°]-90°, and the remainder of the obverse side of the meridian ring carries a table of latitudes for places in Europe, which is continued on the reverse.

On the obverse side of the equinoctial ring the table of latitudes is further continued, and on the reverse and inner-rim are two hour scales. There is simple decoration on the bridge supports. The quality of engraving on the latitude scale is good, but the rest is rather poor. The double occurrence of Budapest in the latitude list is odd. 'P. Beringus Herzog Can: Soreth: Anno 1750' is engraved on the outer rim of the equinoctial ring.
