notes: label: Description
content: This full-keyboard, non-printing electric calculating machine has a gray metal frame and ten columns of light gray number keys. All the keys are the same color. At the base of each column of keys is another key. These keys are numbered from right to left 0 to 9. Each controls a striped metal rod between two columns of keys. When the control key is pushed down, the rod moves up and red stripes show between the keys, between windows in a row of windows at the front of the machine, and between windows in a row of windows directly in back of the keyboard. This indicates a decimal point.
label: Description
content: To the right of the number keys are various function keys, including one for squaring numbers. A row of dials in back of the keys indicates the number set up on the keyboard. A row of ten dials at the front of the machine is used to enter a multiplier. A movable carriage at the back has a 20-window result register and an 11-window revolution register. A small lever between each pair of keys on the carriage can slide to reveal a decimal marker.
label: Description
content: A mark on the carriage reads: SCM MARCHANT. The serial number, on a metal tag attached to the bottom of the machine, is: SK-661050. A mark on the back of the machine reads: SCM.
