Equipment - Scientific Instrument, Nobel Explosives Co. Ltd, Nobel's Explosives Co Galvanometer, Between 1877 and 1926
Nobel Industries Limited was founded in 1870 by Swedish chemist and industrialist Alfred Nobel for the production of the new explosive dynamite in the United Kingdom. Ardeer, on the coast at Ayrshire, was chosen for the company's first factory. Between 1877 amd 1926 it was known as Nobel’s Explosives Company Limited. The business later diversified into the production of blasting gelatine, gelignite, ballistite, guncotton, and cordite. At its peak, the factory employed nearly 13,000 men and women. In 1926, the firm merged with Brunner, Mond & Company, the United Alkali Company, and the British Dyestuffs Corporation, creating a new group, Imperial Chemical Industries, then one of Britain's largest firms. Nobel Industries continued as the ICI Nobel division of the company. Small black timber box with small screw holding back on, and leather handle on top.

Equipment - Galvonometer, 1930 (estimated)
Galvanometers are an instrument used for detecting and measuring electric current. They had a magnetic needle moved by the magnetic field produced by coils carrying the current to be measured, and the earth's field had to be taken into consideration. They were used to detect current in either direction in telegraphy systems, and to test equipment.Post Office Galvonometer. A hinged polished timber case with three brass terminals at the top, and ring (handle) and a dial (0 to 70) with an indictor needle. The opened box reveals wires leading to the terminals with two compartments covered in blue woven material (possibly silk).telegraph works, galvonometer, scientific instruments -
