Brunsviga Adsum 94 T Mechanical Adding Machine for Pre-Decimal Currency - A mid-20th-century Brunsviga Adsum 94 T mechanical key-driven adding machine, specifically designed for pre-decimal British currency calculations. The unit features a robust cast metal housing finished in a textured grey hammer-tone paint. The input interface consists of an eight-column keypad with stepped plastic keys in alternating shades of light and dark green. The keyboard layout is configured for pounds, shillings, and pence (£sd), featuring a dedicated column of keys numbered 1 to 11 for pence alongside seven columns primarily numbered 1 to 9. The numeric register display is located on the left side, showing ten digits behind clear windows. The machine is well-marked with multiple identifiers: the left side bears the embossed model name ADSUM, while the lower right corner features a triangular metal manufacturer's badge for BRUNSVIGA. A riveted identification plate on the side identifies the sole concessionaires for the U.K. and Eire as W. H. Turnbull and Co. Ltd. of London and confirms the item was made in Western Germany. The black-finished base is stamped with the serial number 22-05048 and carries a small model label for the Brunsviga 94 T. This non-listing machine is operated by depressing the keys and using the side-mounted crank handle to register and clear totals.
