I'm replacing all of my downstairs switches and sockets with teh fancy
gunmetal onces from Screwfit (made by crabtree). The only problem until now
was that while they do the slave telephone socket, they dont do master
telephone sockets, and as out master socket is in a prominent position in
the hall, it is going to look kind of odd. I figured I could but a blank
plate fromthe fancy gunmetal range, and a regular master phone socket, and
make something myself.

Use the slave, but keep the master located somewhere out of sight. (you
really ought to retain the surge arrestor and test resistor present in
the real BT master - otherwise you could turn your metal secondary into
what they call a PBX master (i.e. provides it's own ring line) by the
addition of a 10uF bipolar electrolytic cap between pins 2 & 3 on the
socket).

However, on removing one of the two ways light switches, (which I had
ordered a 1g2w gunmetal replacement) I found that it has four terminals.
Thinking about what the two-way wiring diagram looks like, it is now obious
this is a Normally Open and a normall closed switch in one assembly to make
a changeover arrangement. It now seems like 1g2w "intermediate" switches are
available in the bog standard ranges, but not in the fancy gunmetal range.
Arse.

Gets messy but you could use an ordinary switch and a relay instead...
