Oh no! If the tube and its wire are removed, how will one summon the upstairs maid when one needs her services?

You'll just have to whistle out the bedroom window and hope that the gardener's boy is obliging.

I wouldn't regard the gardener's boy as qualified to carry out the upstairs maid's services. The two jobs have completely different skill-sets.

I don't get a clear picture of where exactly it runs in relation to the fireplace brickwork. If it's original and positioned with the fireplace in mind, why not just cover it up again? If not, trace it with a metal detector and find out where it goes.
Could we have a picture from a longer perspective?
