Works with an electric motor, very good condition
A mechanical calculating machine with unprecedented abilities for it’s time.
All keys are present and as far as I know everything is still in working order.
NB. not all the options have been tried or tested by me!
An explanation of the all keys will be included.
For those who wish to know what all the possibilities are - a Calculator Operators Manual on sale on the internet for $9.
The font used for the name “Monroe”, and the fact that it is a dark grey machine, and that the serial number is 534201,
confirms that this machine is from the year 1951.
From 1953 onward these were produced in a two-colour housing. The production ran through to 1956.
NB. the machine will keep running on when division, the DIV (divide) function is used. There are keys to stop by means of the round button
on the right side which must be held tightly. In addition, a limited number of digits (0) are partially worn away!
Weight: approx. 12 kg. Width: 34 x Depth 28 x Height 20.
