- Description
- This full-keyboard non-printing electric proportional gear calculating machine has a blue metal frame with a black carriage. It has ten columns of green and white all-plastic number keys. At the base of each column is a gray tabulator set key. These keys are numbered from 1 on the right to 10 on the left.
- Right of the number keys are a small switch; line up, division, and stop keys; subtraction and addition bars; a non-shift key, a repeat key, and a negative multiplication bar; and two carriage shift keys. In front of these are clearance keys for the tab set, the keyboard, and the dials. Right of these is a column of ten keys for automatic multiplication. Odd digit keys are concave. Above the number keys is a row of ten windows to show a number set up.
- Behind this register is a movable carriage with an 20-window result register and an ten-window revolution register. The registers on the carriage have reversible decimal markers. The motor is at the back of the machine, inside the case. The machine has four rubber feet.
- Marks on the sides and back of the machine read: MARCHANT. A metal tag attached to the bottom reads: 10EFA-351117 A piece of tape atop the machine reads: 2-130. Remnants of a black plastic label attached to the bottom of the machine read: Figuremaster.
- According to the donor, a collector of calculating machines, this example was manufactured in 1951 and originally sold for $787.00.
