Mid 20th century
In 1958, IBM's Time Equipment Division was sold to the Simplex Time Recorder Company. However, in the United Kingdom ITR (a subsidiary of IBM United Kingdom Ltd.) was the subject of a management buy-out in 1963 and reverted to International Time Recorders. In 1982, International Time Recorders was acquired by Blick Industries of Swindon, England, who were themselves later absorbed by Stanley Security Systems.
