A manual telephone exchange, manufactured by British Ericson, History Originally in use at Cohuna. When Cohuna was converted to automatic dialing this exchange was relocated to Harcourt, to become the third and last in a bank of three exchanges. At this time Harcourt exchange was expanded to 260 lines. It was connected to the district central exchange at Castlemaine. Operated by mains power with battery back-up. Harcourt exchange was operated by Betty McLean, Miss Mitchell, Josie Hogarth, Mr. & Mrs. Heighway, Bill & Valerie Milford, Irene Bolitho and others. Decommissioned approx. 1970. Incoming calls prompted the fall of a shutter. The operator made the connection by plugging the line into the number requested. While responding to calls the operator needed her hands free to jot down the billing particulars or to write out each telegram. Nearby stood pigeonholes with various items of stationary. Many telegrams were received each day, particularly advising fruit growers on interstate markets. Most telegrams were phoned through by the operator.
