  Hollerith Type III Tabulator - manufactured in Sweden
  A tabulating machine is an electromechanical machine designed to assist in summarising information and, later, accounting. Invented by Herman Hollerith, the machine was developed to help process data for the 1890 US Census. It spawned a class of machines known as Unit Record Equipment, and the data processing industry.

Its basic function is to count and / or add from punched cards and then produce results or reports on dials (early models) or visible counters (as here), or print them on paper and / or send them to a separate card punch or other device so they can be used in subsequent calculations.

This machine was acquired in 2015 by the museum, and was donated by IBM Denmark. Models of this type date from the early 1920s. This is an early example, built by IBM Sweden, with serial number 10.

In the UK, prior to the end of WWII, machines such as this were built under license from IBM by The British Tabulating Machine Company.
