Compass dial

Compass dial set in a brass box with a brass screw-on lid. The dial consists of a folding gnomon hinged to the hour plate, which is cut away to reveal a revolving compass underneath. Around the rim of the hour plate is an hour scale of Roman numerals. The compass card is printed from a copper plate, is coloured, and displays a 16-point compass rose marked by English initials. There is a scale for degrees around its outside edge and a glass plate covers all. The lid also carries a compass rose, pasted on to its inside, with 32 points and marked in black and white. 'C Stedman London' is signed round the central flower decoration both on the compass card and on the lid. The standard of engraving on this dial is not very high and it is similar to AST1143.
