original early 20th century antique american industrial lightweight diminutive laboratory bench early electrical resistor or decade box designed and fabricated by or for the c.h. stoelting co., chicago, il. the well-maintained solid walnut wood cabinet with corner box joints retains the original beveled edge base or surrounding trim with mitered joints. the top of the resistor cabinet contains cast brass knobs or caps with coils of resistance wire concealed under the black bakelite platform. the detachable shunt pegs contain black bakelite knobs. the decking is affixed with brass screws throughout. the antiquated testing device was used in a general electric laboratory. the wood cabinet retains the original varnished finish. very clean and well-maintained. the resistance decade box or resistor substitution box is a device containing resistors of many values, with one or more mechanical switches or detachable "pegs" which allow any one of various discrete resistances offered by the box to be dialed in. usually the resistance is accurate to high precision, ranging from laboratory/calibration grade accuracy of 20 parts per million, to field grade at 1%. all types offer a convenient way of selecting and quickly changing a resistance in laboratory, experimental and development work without needing to attach resistors one by one, or even stock each value. the range of resistance provided, the maximum resolution, and the accuracy characterize the box.
