content: This sturdy German stepped drum, manually operated non-printing calculating machine has a brass and iron case painted black. The eight-digit entry levers are linked to dials that record the number entered and to steel stepped drums. Levers in front of the dials zero the entry. The addition & multiplication / subtraction & division lever is on the left, and the operating crank is on the right. The plate at the front is easily removed to show the levers and bell.

content: In back of the levers is the carriage, with nine revolution register dials and 16 result register dials. The zeroing bars for these registers are on the right of the carriage. A knob for lifting the carriage is on its far left. When the entry in the result register becomes negative (as in subtraction or division), a bell rings. It rings again if a number is added to bring the total to zero or more. The entire machine has a steel cover painted black.
