Markings and inscriptions "Only the right half of the dial surface is preserved. Five hour lines (7, 8, 9, 10, 11) and parts of three day curves are visible in the photograph. Petrie found a configuration of lines on the top surface of the fragment which he suggests were used to align the instrument." (Gibbs 1976)

Graßhoff (2015) states that this dial is in Tunisia, quite obviously because of a confusion with the sundial that shares its page in Gibbs (1976). Gibbs herself could not locate the dial and used Petrie's photograph and drawing to characterise the dial. The Petrie database confirms that it is with them in London. 

The Graßhoff (2015) bibliography locates the wrong plate in Petrie (1911): the photograph appears in Plate XVI, not Plate XV.
