This is fabulous French pantographic lamp. 
It shows age related wear aplomb, which is exactly what we love about it! It’s history, it’s story! 
It can be extended and tilted. Tilting can be made at the wall end, using the wing nut and the shade tilts too! 
It’s not a huge shade so would sit neatly beside a bed or sofa/chair. 
It has been rewired by a qualified electrician and PAT tested. It can be plugged into the socket, meaning no need to be wired into the wall and there is an inline switch on the cable to enable turning off and on. Alternatively it could be hard wired by an electrician.
