ITR’s acquisitions gave them a huge range of dial, key, and card time recorder clocks, many of which found their way into the UK. The most common ITR models which were destined for the UK market can be seen in the images below, taken from the IBM Archives. For a more comprehensive collection, the IBM Archives website’s ‘Clock corner’ reference room pages (available via the Links page) provide information and pictures of most models sold by ITR. A useful list of IBM products and clock models is available via the Documents page, or via their Archives website.
