This is a brass combination compass and sun dial with lift-off lid and suspension ring. The front of the lid is labelled Coronation of Elizabeth II, June 1953 with a crown in the centre. The back has intricate instructions for using both the sun dial and the compass. When the piece is opened the inside reveals a glass-covered compartment for the compass. The sun dial component has a lift-up pointer for catching a shadow and a surrounding ring of Roman numerals (1-11). Inside the lid is a rotating disc which is marked with a variety of worldwide major cities and this is in front of another marked area for the time of day. The condition is good for age although there is some staining of the brass. Portable sun dials and compasses would be intriguing items to collect from the scientific point of view and this example also includes the added interest of being a piece of Royal memorabilia. Diameter 1.75 ins (4.4cm). Depth 0.6 ins (1.5cm). Weight 80 grams. This item appears in my book “How the Watch was Worn, A Fashion for 500 Years” on page 216.
