Help: Ratchet Adjustable Lamp Stand

Hi all, I was wondering if anyone could help me identify this lamp stand? How it should originally look ie what kind of hanging lamp does it originally have, or even some ideas on what would look good. Finally, what it is worth, either in its current condition, or restored.

It is adjustable in height from 140cm to 170cm, hard wood - no wood worm, overall good condition but is showing its age a bit.

Thanks in advance!

Oli

 

I can’t quite tell where the socket would go on yours, here’s some others
