Description
This mechanical calculator, from circa 1950, was made by Guy’s Calculating Machines in England, These large devices were sold directly to businesses.

Earlier mechanical calculators could only do addition and subtraction. However, this Muldivo mechanical calculator was more advanced and could do multiplication and division. The result was printed on paper. While quicker to use and requiring less skill than slide rules, the devices had fewer capabilities.
