Not to blow my own trumpet here... but I have a page of phone wiring diagrams [including the 746]
here .
Also, interesting to note the reverse dial due to NZ using revertive impulsing (where the number of pulses were the DIFFERENCE between the number dialled and 10) instead of the British and American method. I believe one or more of the Nordic countries may also have used that form of dialling? I know the look of that phone well, I have about 100 of them sat in the attic.
