A unique collectible from the Victorian era in England.  This is an Elliot Brothers charting instruments set in a mahogany wood box which belonged to G.B. Chalon.  His name appears on a small plaque on the box and on some of the instruments inside.  The instrument set which was used either for nautical map charting, mathematics or engineering drawing includes what we think are all of the original items with a lift out tray.  This charting set includes ivory handles on some of the instruments especially the protractor (ruler) which is all in ivory.  The ivory protractor, marked: Elliot 449 Strand London, is therefore presumably made after the company moved to their Strand St. location in about 1867.  The two slots in the protractor were for a ribbon so that the naval officer or other user could wear it round his neck. This is a fantastic antique Victorian era collectible for those who love scientific or nautical/naval/maritime items. Dimension: 19 cm x 9.5 cm (7.48 inches x 3.74 inches)
