I mentioned this is another thread and said that I would dig out the old cable code which was used in the U.K. in years gone by.

So for anyone interested in long-obsolete systems from an ocean away, here are two pages which describe the coding and cable makeup from Atkinson's "Telephony," 1950 edition:

It's not shown in the chart, but the standard 4-wire cable used for subscriber premises wiring used the solid colors blue, orange, green, brown.

My apologies for missing this question over a month ago! shocked

The cables listed as "triples" on those pages were typically used for internal exchange wiring. The third wire of the circuit was for control -- The sleeve connection on a cordboard jackfield or the P-wire on Strowger switches (used to mark busy trunks and control the holding of the connection).
