I have a bit of a soft-spot for vintage telephones. Actually, old school stuff in general.
However, I can't be bothered mucking about with classic cars, or renovating an old house, so I occasionally tinker with vintage phones instead.
You see, both my parents worked in telephones, my father was out on the road as a telephone technician, and my mother worked as a technician at the local telephone exchange.

My cousin and I using connected BPO 332 phones, Wellington NZ, July 1979
On deregulation of the New Zealand Post Office in the late 1980s, Dad became a telecommunications contractor.
In the 1990s, I joined his company as an assistant technician, for 5 years it was my school holiday job, I think he wanted me to take over the business.
Thank goodness I decided to work in architecture though, as there's not too many landlines around these days!
Below are some useful NZPO manuals for telephone technicians from a bygone era. I've put them below as a reference because, well, why not?
You can even download them on your telephone! (there's a lot of data here, so please make sure you are on a wifi network first)

Telephone Exchanges
My Mum used to work in the telephone exchanges, and I would visit her after school and sometimes socalise with the technicians in the break-room.
To give you an idea of the thunderous noise produced by the mechanical equipment in the exchange there is a video below... (sound on please!)
Andy Wibble, a former NZPO technician explains Step By Step (SXS) exchanges;
"...(This is a foreign SXS) exchange, very similar to the ones I also worked in during the 70s. We used to be able ‘tune out’ the noise but it may explain my hearing loss in one ear maybe! Around a quarter way through this video are shown what looks like two motors with odd rotating cams on the front. These are ringing machines that generate all the tones and ringing current to make the telephone bells ring. The cams have raised bumps that operate relay springs to create the correct cadences for the various tones. This is all done electronically now of course!"
All of this technology originated in the 1920s (and was still being made as late as the 1970s) and it is now completely superseded by computer hardware, software and the fibre-optic cables of the internet
Today systems such as VIOP , WiFi Calling, and SIP, can be accessed wirelessly through your mobile telephone, to a point where telephone exchanges have largely been replaced by Data Centres.
With thanks to Wibbles World for the memories.

Below is a PABX system I want to eventually build using all the phones in my collection...
Note: I will not include the generator phones on extension 4 and 5, I will run these two as a seperate closed battery (CB) system as it would have been in the old days.
