The APO's convention was that wall phones would receive the odd numbers and table phones the even numbers.
Tele No 1 ............Tele No 3...........Tele No 5 .........Tele No 7........Tele No 9.........Tele No 11
Tele No 13..........Tele No 15........Tele No 17.......Tele No 19......Tele No 21.........Tele No 25
Tele No 29............Tele No 31......Tele No 35 ........Tele No 41.......Tele No 45...
In the late 1930s the numbering system was revised. The surviving old phones were renumbered into the new series and new models were added. There is some overlap, therefore, between the older Tele numbers and the new Type numbers. Where possible I have included the new Type numbers in the body of the text for older phones. An entire series of phones could now be numbered within the one basic Type number. See the 300 Series as an example.
