Development of the Armoured CT1
| As CT1s were increasingly placed in less supervised locations, theft and vandalism soared. In response, the Sydney Workshops developed a sturdier variant: the Coin Telephone No. 1 Reinforced, more commonly known as the “Armoured CT1.” This updated version featured a heavier 18-gauge steel casing, a wraparound front panel with reinforced steel, and a heavily protected coin tin fitted with a robust steel lid. The unit was painted in durable grey or dull green hammer-finish paint to resist scratching. Though visually austere, the reinforced model was effective. Some units were later refurbished in a brighter gold tone in an effort to improve their visual appeal. Despite the lack of aesthetics, function took precedence — and the Armoured CT1 proved a successful deterrent against vandalism. |
| VANDALISM MODIFICATION: The CT1 instrument underwent three major changes externally to cope with vandalism more effectively. Fig.28 illustrates the early version with front lock and pressed metal door. This was soon modified with a reinforced front door lock and coin chamber housing (later side Chubb lock as with A.B. Multi-Coin Boxes) and reinforced diaphram of steel encasing the mechanism (Fig.29). The third type is the totally reinforced CT1 which had a heavy steel outer shell. At their peak it is estimated that 9000 including all types were in use in Australia. By mid 1970s they were being phased out in preference to the existing A.B. Multi-Coin Box and the new Coin Telephone No.3 and the CT1 were being installed only in safe locations on private property. There was a CB version produced for country exchanges which had the dial blanked, calls being operator assisted. Tariff changes on all versions saw the originals change from five, ten and twenty cents, to ten and twenty cents. |
