746

In 1967 the 746 model was introduced as a replacement for the 706. The seat cover is slightly different from the 706 types, although it retains the same overall appearance. Initially, the phone case codenamed Mark 1 (1/DCO/718) did not have a recess for the handle which resulted in the handset sometimes sliding forward and this was enough for the phone to stay off the hook. The seat-casing was later modified with the Mark 1A code (2/DCO/718) and the problem was solved by creating a recess, with raised sides to prevent it from sliding forward. Many parts of the 740 and 746 are identical to those of the 706. The 746 was later manufactured with the new RJ-11 type cable and renamed the 8746. It was also equipped with high impedance bells i.e., two 2000ohm ringing coils. Available from 1970 to the late 1980s as maintenance stock. At the front of the seat-cover there is a protrusion which secured to a recess in the base at the same point. At the rear it was secured with a fixing screw. The base of the 746 was made of mild steel with a black enamel finish. The ringing mechanism is screwed into the base of the device. The first telephones were equipped with the 59C-1 ringing mechanism. The type was equipped with the 21FA dial with transparent perforation. The 746 had the following variants: A, B, C, D, F, G, L, R, GR, S, T and W. Variations on the basic type of device usually involved a different ringing circuit or the addition of a grounding button (R and GR variants dating from after 1981). The 746 was released in Australia as well as New Zealand under the code No. 101. It was available in seven basic colors, black, blue, two-tone green, two-tone grey, ivory, red and mustard. A dark brown version was later added and the 746 was marketed as the Yeoman series. There were also various two-tone variants including pink, orange and azure blue. Its weight was approximately one kilo and its dimensions were, W: 21.5cm. x D: 16cm. x H: 14.5cm.
