The main frame and sub-frame assemblies and dial-plate are all numbered 460. There are no marks behind the dial.
A similar but less elaborate presentation chronometer, McCabe No. 448, was exhibited at Aspreys, Exhibition of Marine Chronometers, 1972, exhibit No. 45, sold with its original invoice, dated 1856.
The present chronometer is of an even grander design than No. 448, the engraving is of McCabe's best quality and the decoration virtually stands proud of the background. A carriage clock by McCabe with similar engraving is illustrated in Derek Roberts, Carriage and Other Travelling Clocks, Schiffer, 1993, fig. 20-16 a, b, c & d.
The cypher above the motto Heavens Light Our Guide is thought to be for the Maharaja of Kashmir. The opposing side is indubitably Queen Victoria's Royal crown and cypher. The words Heavens Light Our Guide was the motto of the Chivalric Order of the Star of India, instigated in 1861 by Queen Victoria. It would therefore seem likely that this chronometer was made to order as a diplomatic gift to the Maharaja of Kashmir, who had recently been instated by the British, presumably to curry favour.
