Physical description:

A set of drawing and surveying instruments by J. Halden & Co. In a two-tier wooden box. The wooden box is stained a dark brown, and has a brass plate on the lid with no inscription, a brass plate for the keyhole, and two brass hinges. The lid of the box is lined with bluey-purple silk (?), and bears the words 'London // J. Halden & Co. // Manchester' in gold. The upper tier of the box is lined with bluey-purple velvet (?) and is shaped so as to hold the instruments firmly in place. On either side is a length of ribbon in the same colour for lifting this tier out of the box – one ribbon is now missing and the other is torn. The lower tier is divided lengthways into three sections – the outer two are lined with same material, while the central section is un-lined. The upper tier contains fourteen items, some of which are attachments for each other, ranging in length from 75mm to 165mm. They include a compass with extension bar and fittings, dividers, two bow compasses, three spring bows and three ivory or bone handled ruling pens. Some of these instruments are marked 'J. Halden & Co.' The lower tier contains two pencils, two tubes of spare pencil lead, a pen nib, and the key for the box. The pencils and tubes are marked 'L. & C. Hardtmuth, Austria No.5'.
