Hi Ian, what I would like to know, and perhaps the OP too, is when did the GPO begin the wholesale replacement open-wire drops with the CCS figure-of-eight pairs in suburban streets?

I would guess our street was rewired between 1960-1965, but childhood memories can be deceptive.

My recollection was that all the drops on a given DP were renewed at the same time.

Incidentally, our exchange was MRCHE, one I know you have worked at.
