Antique rosewood veneered box of drawing instruments

This is an antique rosewood cased set of brass and steel drawing instruments. The instruments include: a bone-handled scribe, dividers, and two sizes of compass both with changeable legs. The box also has an ebony 6" parallel rule, two boxwood set squares, a French curve, a brass protractor, a bone-handled pencil, two wooden pencils and a tube of leads.
The box has a few marks consistent with ordinary light use and its age. The purple velvet lining of the tray has faded a little in colour. It has an unmarked brass tablet on the lid and a brass key plate. The dimensions of the box are: 18cm x 11cm x 4.5cm.
The box will be sent by Royal Mail Standard Parcels which takes 3 - 5 days for delivery.
