This full keyboard printing electric adding machine has a steel frame painted black (and green under the keyboard), and eight columns of black and white color-coded plastic keys. A green clearance key and subtraction and addition bars are right of the keyboard, as well as a repeat lever. Above the keyboard is a row of eight number dials under glass that shows the total (this is called a visible adding dial). Behind the dials are a non-print lever and total-subtotal lever on the right and a non-add lever on the left. Behind these is the printing mechanism and a 31-cm. movable carriage. There is a two-colored ribbon. Under the printing mechanism is the motor. Part of a roll of 6 cm. (2 1/2”) paper tape fits in the printing mechanism behind the carriage. The carriage has rubber handles, and the machine has four rubber feet.
