The ornate engraved paper dial is labelled “sold by P & G Dollond” who worked at St Paul’s Churchyard from 1805-20.They became opticians to George IV but Peter Dollond died before the appointment was activated.They are a rare maker and very few of their instruments survive.The dial plate is engraved in bold black wax filled numerals,the gnomon is decorated with an engraved border on one side only.The case is in a dense mahogany and is closed via two inset triangular pinned hinges and a single brass hook and retaining pin.The lid is hollowed to accept the gnomon when closed.The blued steel needle has N & S in gilt and has an octagonal boss with crennelated glass leveller,and is dampened for transit by a locking pin in the upper surface of the base,which,when depressed,locks the needle against the glass.
