Telecom Rotary Dial Telephone - Grey

Released in 1962 in the PMG days, this phone was an Australian-designed model taking advantage of modern plastics and electronics. The original version, the 801 series, is distinguished by having the numbers around the outside of the dial. There were actually three dials used in the range as a standard Australian dial was not yet being manufactured. Each dial came with an adapter plate with the numbers correctly located for that model of dial. When the standard dial became available in 1970 there was a minor update and the numbers were moved under the fingerholes and the new range designated 802 series. This did away with the need for the adapter plate. This caused some problems for the visually impaired and Telecom released a Large Number Ring, a plastic ring with raised black numbers which simply stuck on to the face of the phone around the dial. Many models were derived from this basic phone.
