In the 1980's I after looked after the pabx telephones at Birmingham University for GPO/BT. They also had a Reliance engineer who looked after the PAX phones. One day, he (and his apprentice) approached me to ask how to put an extension off a single telephone AKA plan 1a. So I ripped a sheet out of my notebook and quickly drew a two telephone p!an 1a complete with strapping and cord colours.
He duly thanked me and as I walked away, I couldn't help feeling a bit smug when I heard the apprentice say "Wow, he did that straight out of his head!".
i know I'm not the only person who could have done that in those days but it's testament to the GPO training we received, which in my opinion, was second to none.
I love these old diagrams and the people who could draw such things.
