Antique course indicator constructed in high grade polished steel and oxidised brass, gilt brass milled head, rotating 4″ azimuth circle divided into four sectors with cardinals, plotting indexes. The upper part marked “Lilley & Son, London,” “Patentees & Manufacturers,” the lower “No 111.” The verso with moire finish.
Contained in its original plum velvet lined Moroccan leather over wood case, retailer’s label to inside lid with Royal Warrant, and marked “Francis M. Moore, Chronometer, Watch Maker & Optician, 102 High Street, Belfast and 23 Eden Quay, Dublin.” Together with its original instruction sheet bearing retailer’s ink stamp, which indicates it originally retailed for 30 shillings.
A gem, wonderful engineering and aesthetically attractive. It is thought these were manufactured in very small numbers, perhaps well less than 500. The instrument remains in exellent original condition with some signs of handling and age but very crisp overall. The case has been the subject of restoration, the leather to the top having been replaced, otherwise it remains completely original. The instruction sheet remains intact with some ageing.
Absolutely a collector’s piece.
This simple brass instrument was designed to aid chart work. According to the instructions, it was meant as a replacement for parallel rulers, in particular in order to avoid the wear and tear caused by constantly sliding them around the chart. To use it, the straight edge is placed on the chart between the departure point and the destination, and then moved until the nearest meridian line can be seen through the hole in the centre of the milled wheel. The wheel is then turned until the north point of the disc aligns with the meridian line. The true course is shown by the index line at the side of the instrument.
John Lilley founded his company in London in 1812 and the firm thrives today as Lilley & Gillie.
