Calling dial from a Strowger telephone, manufactured by the Automatic Electric Company, United States, 1906.
E A Mellinger of the Automatic Electric Company redesigned the Strowger system so that only two wires were needed to connect each telephone to the exchange. It used this type of dial, known as the 'sunburst' from the design in the dial centre. The design was produced between 1904 and 1914 in two types, one with ten finger holes and another with eleven.
