Among the finer examples of a complete English shagreen draughtsman’s etui circa 1800 in exceptional condition with owner’s signature and date. Features 10 instruments including matching boxwood sector and scale rule, brass protractor, and complete drawing instruments comprising small and large dividers with fitting attachments for measuring, pencil lines, dotting, and inking. A turned brass pen and fine brass-mounted pencil complete the set. The pen, dividers, and inking attachment have butterfly style steel and brass thumbscrews.
The case is in perfect condition with sharkskin exterior and brass fittings. The interior features marbled paper lid, yellow paper lining and printed matter from books of the period. There is a maker’s series number in ink on one side of the lid, and on the other side, a previous owner has signed the set in pencil, unfortunately not entirely legibly – it may read “R. Frögasse 1815.”
The dividers have a refined flat design with all brass joint instead of the usual steel screw. This is an unusually fine and complete set of the period in outstanding condition.
