Yeah she's an old one! Ggl-8. Before they added the uk, or 0x designations.
The two pieces of vertical grey metal are still there, riveted on (flew a drone over roof to take a look), but the horizontal section the metal has fatigued and fallen off.
Ideally could replace whole thing for a gpl uk08 as same size and top hung so that it will actually open....
So it was installed to replace the 1880 ish stairwell light. Has a flat decorative glass ceiling over the actual stairwell which is still there in mostly one piece. Will look nicer when cleaned up.
Velux plonked on top of roof /boards (it's slate, felt then timber boards), so a mid pivot can't open more than 2cm due to the rafters being below.
Originally that was way onto roof, to do maintenance etc. So since this thing was done the building has gone downhill, as no one wants to pay £500 for scaff each time to get up there.
So in future might just replace whole unit with a top hung velux gpl type, so that can easily get on the roof once more. Only around £550 which i thought was very reasonable price tbh! But right now my indoor job list is massive

There's usually no need to work on them from the outside. The sash can be removed completely, but yours would be a heavy bugger and it's not really needed. Just rotate it to vertical and there would be enough space to work.
They can pivot right around and the shootbolt locks into the hole in the bottom of the frame, for a maintenance position / cleaning.
Mines a GGL-804. So the next generation. Same width but not as tall.
Yours will probably be a similar setup, but likely a bit different. My version has the vent filter clipped onto the top casing.
There's a screw in either end and the top casing fits under the top flashing.
