Brief Description: Horary quadrant with concentric scales and slotted index. Reverse carries a dhurvabhrama-yantra: circular scales with pointer piece carrying three indices and a handle arm all at right angles to each other. Two pinhole sights on one edge.

The instrument is described as L004 in S.R. Sarma, A Descriptive Catalogue of Indian Astronomical Instruments (Duesseldorf, 2018; available at http://www.srsarma.in/catalogue.php). It is almost identical with another in the Paris Observatoire (described by Sarma in greater detail as L003).

The inscriptions on both instruments state that they were made by the goldsmith (sonī) Morarajī for Premajī Paṇḍyā on the day corresponding to 2 June 1815.
Primary Inscriptions: Sarma translates the two Sanskrit inscriptions as "Today, in the city of Bhuj, during the victorious reign of Mahārāja Rāu Śrī Bhāramalajī, this dhruvabhrama-yantra of Paṇḍyā Premajī, son of Śrī Paṇḍyā Vīrajī, was made [by] Sonī Morārajī." and "In the Saṃvat year 1872 of the reign of the glorious king Vikramārka, in the current year 1738 of Śālivāhana era, on Friday, the eleventh day of the dark half of Jyaiṣṭha. On this day the sun’s tropical longitude (sāyano raviḥ) is 3|0|0|0; equinoctial shadow (akṣabhā) 5|0; equinoctial hypotenuse (akṣakarṇa) 13; terrestrial latitude (akṣāṃśa) 22;30. This instrument [should be employed] always in Kutch, Saurashtra."
