Six engraved hour lines, including the meridian, are preserved on this southeast-facing half of a vertical deviating dial. The equinox and two solstices do not extend beyond the first hour line. Although the dial has been squared off along the left edge, a portion of the curved border remains. The top and right edge are smoothly perpendicular to the dial face. A large engraved B is preserved at the left end of the top edge. Evidence at the junctures of the wide hour lines and the equinox indicates that the former were engraved last.",
