Calculator - Peerless

Estructura del mecanismo
Función	This electromechanical calculating machine has a full keyboard with 9 rows of figures from 1 to 9. There is a 9-figure input register, an 8-figure counter and a 13-figure totalizer. It functions thanks to its electric motor (220v) but also manually by using the crank located to the right of the keyboard. Two keys are used for carriage shift, and small knobs enable the partial re-set of the counter and the totalizer. The technological advance here is the possibility of multiplying a figure by a multiplier from 1 to 9 using the keys located on the right of the machine.
