SCM Marchant Model 8CD Calculating Machine

Description
This full-keyboard, non-printing proportional gear electric calculating machine has a gray and tan frame with eight columns of color-coded gray and tan keys. Above the keyboard, a row of eight dials indicates the number entered. To the right of the number keys are division, stop, subtraction, short cut multiplication, addition, and multiplication bars. Also included are two carriage shift keys and three clearance keys.
Behind the entry register is a movable carriage with a 16-digit result register and an eight-digit revolution register. To set decimal places, one uses sliding decimal markers. A mark on the carriage reads: SCM MARCHANT. The serial number, indicated on the bottom of the machine, is 8CD - 705041.
The donor was a certified public accountant who had a collection of calculating machines. The date of manufacture (1964) and original cost ($475) are provided by him.
