My sister, who was once a GPO telephonist in Oxford, has recently passed me a list (prepared by our late mother, who was also a GPO telephonist there) of exchange codes used, I believe, for charging dockets. This list will be specific to Oxford as some of the smaller distant exchanges are given as subsidiary to other major exchanges, from which, no doubt, some of the codes would be prefixed "OF/". I attach a transcription of this list in case it is of interest to the telephone afficionados here and in the hope that a little more information is available about the context in which these codes would be used.
