Authentic antique decade resistance box manufactured by Griffin & Sons, London, dating to circa 1900. A classic precision laboratory instrument used for electrical testing, measurement and calibration. The instrument is housed in a solid polished wooden case with a warm aged patina and an original Bakelite top plate, an early synthetic material widely used in pioneering electrical equipment. The top plate is clearly maker-marked “GRIFFIN LONDON”. The upper section features precision brass resistance modules arranged in switched stages, allowing calibrated resistance values to be introduced into an electrical circuit. Period brass terminals and selector posts remain in their original configuration. A green period label marked “100 OHMS” indicates the resistance range. The layout and construction are characteristic of early scientific and educational electrical apparatus used in laboratories, universities and technical institutes in the late Victorian and Edwardian period. The visual presence is particularly strong. The contrast of aged wood, dark Bakelite and naturally patinated brass creates a refined industrial aesthetic, while the geometric arrangement of the resistance blocks gives the piece a sculptural, architectural quality. A desirable collector’s piece representing the formative years of electrical science and early electrical materials. Suitable for scientific instrument collections, early electrical equipment collectors, industrial interiors, museums and educational displays, as well as film and period set props. Good original antique condition with visible age and use wear. The wooden case shows patina and surface marks consistent with age. Minor cosmetic wear to edges and base. Brass elements retain an attractive natural patina. The Bakelite top plate is original and well preserved. Electrical functionality has not been tested.
