History of the GPO
The General Post Office (GPO) was the United Kingdom’s national postal and telecommunication service until 1969. In the 1930s, the GPO was responsible for expanding the national telephone network, installing thousands of telegraph and telephone poles across Britain. Ceramic insulators were the standard component for mounting telephone wires, preventing electrical faults and protecting the metal cables. Each insulator carried the GPO stamp and often a year of manufacture, making them a valuable reference for historians and collectors.
