Shower screen part missing

[Ac71]

Hi .Just bought a 2nd hand over bath hinged shower screen, come to put it up and i feel there are some screw rods? missing of some form that connect the glass to the pivot that go in the holes i have pictured..
Its an old brand ..(Selecta)..so cant see anything online to help me, anyone had any experience of fitting this type of screen? I have included pics to try make clearer what im talking about. thanks in advance

Erm - I think someone's at it I'm afraid to say, they wouldn't normally be 2 separate parts, the screen and the hinge bar that slots into the wall channel normally all comes joined together. If it's separate like that then I'd say it's been (edit) broken.
