Hello Geekzone.

Can any body answer what this might be?
No markings on the plastic cover and on the inside it has two, 'line' & 'inst'.

It was suggested to be a ringer for the POTS land line but there is a lot of meaty solid copper core cables in there.
The house is a 1950's build.

I would like to remove it along with the wall paper then fill the hole.

Pictures were taken with power turned off at the mains board as a precaution.

Cheers all,
Jeremy
