As requested, below are two images that show my three BT boxes along
with the connecting wiring.

The image named 3sockets shows the cable that enters the upper BT box
enters from outside near my window frame, as you can see it goes in to
the upper box; this is connected to the lower BT box and from there a
further wire goes to the conventional BT socket. The dark cable that
goes down into the skirting I cannot comment on, I do not know what it
does or where it ends up.

The image named colours shows a closer look at the wiring and wire
colours.

Mmm - the term "rat's nest" springs to mind!

My guess is that the grey wire which comes up behind the skirting is
actually the incoming cable from the exchange - unless you know differently?

The dark lower junction box would originally have had a telephone wired into
it - the large slot at the LH end fitting the square grommet on the end of
the cord.

The brown box was an extension socket which allowed a phone to be plugged in
and removed - using a 1/4" jack plug rather than the current modular plug.
In those days, the bells were wired in series so there had to be a switch
operated by the jack plug (the shiny bit in the middle) which provided
continuity to the other phones when that one was unplugged. [I installed a
system like that in my house many moons ago!]. The wire coming out of the
top left of that box presumably goes to other extensions - Sky box or
whatever?

At some point someone decided to fit a modern(-ish) type of master socket -
and brought its connections out to the dark junction box where they could be
doubled up where needed. This is was I suspected earlier.

Where does all this get us? Not really sure except for saying that if it
were *my* house, I'd be ripping all of that out, installing a new NTE5 with
filtered faceplate, and re-wiring it all properly and neatly.
