If you look just in front of the right hand leg, there's a small grey box with a dark grey splodge on it, that was the control panel and just out of sight is the locking arm for when it was at the top.
It was powered by water from the London Hydraulic Company and at some point converted but I can't remember if it was still water from a tank or oil.
The capstans may also have been water powered.
Below there's a black door with yellow railing's, that was the entrance to the CM&EE Lighting Dept.
If you stood with the BRUT behind you, under the arch to the right was the Plans arch, to the left the Lamp arch and I believe around there somewhere, was the Dead arch used during WW1.
Below where the photo is taken, there's a road that I think took you out onto Leake street, roughly were the car park is now.
