This window sits above our (sort-of) 3/4 glazed french doors onto our balcony.
It looks like somehow this rod should turn, allowing the window to fall back into the room but we've had no luck so far. The only part that appears to move is that the rod (?) can be lifted up and down a few centimetres which shuts or opens the window a tiny bit.
The window is quite high up and start about 8ft above the floor and requires a ladder to reach.
I've tried googling a number of different window styles and can't find other similar windows, or even how to open it.
The mechanism to open looks very similar to this 'preston system opener': It looks like the mechanism is similar to a 'preston system opener': https://www.ironmongerydirect.co.uk/product/preston-system-opener-bright-zinc-plated-311878
