The seller has two complete sets of these - one in Ivory and another in Grey.

It's really unusual to see a complete set with all of the junction boxes and control equipment, but I'm not sure who's going to fork out £999 for one

Some of their items have been relisted a few times over. A limited market and pricey with it.

BT - we were having that same conversation a few weeks back. Strip it down. Rebuild this. Find the fault we planted. Now here's another.....
