Production of the 843 began in Northern Ireland in August 1972. It had a new style of housing in beige with the clock face now printed on a polished aluminium fascia. The control was now achieved by a circular switch on a clear perspex cover. It continued to use the large brass clock motor, which had now been in continuous production since 1947.
Marketing materials described it:
Chrome on copper kettle makes four cups in your own teapot. Clear clock and simple dial switch – useful when you’re sleepy! Magnolia with opal lampshade. Base only 7″ by 8.5″
In October 1973 Goblin agreed that the 843 was to be replaced by a new model number, the 853. This new model was launched in Autumn 1974.
