Description
This full-keyboard, non-printing electric proportional gear calculation machine has a metal frame painted two shades of gray, and ten columns of color-coded gray and light gray round plastic digit keys. To the right of the keyboard are a variety of charcoal-colored function keys. Right of these is a column of square plastic keys used in multiplication. Right of these keys is an on-off switch. Behind the digit keys is a row of ten dials showing the number entered.
The movable carriage behind the entry register has a 20-window result register and a 10-window revolution counting register. Under the windows of both of these registers is a row of metal flaps used as decimal markers. Under the decimal markers for the revolution register are ten rectangular buttons.
A mark on the left of the carriage reads: SCM MARCHANT. A metal tag attached to the bottom gives the serial number 10CM-671351. A paper tag on the bottom has a list of United States patent numbers, the most recent of which is 2973981. A mark on the back reads: FICA (/) 63180. A nearby mark reads: SCM.
The donor, a certified public accountant, had a collection of calculating machines. He indicated that the machine was manufactured in 1963 and originally cost $755.
