My mother had some PVC DG French windows fitted a few years ago. They open outwards, with hinges on the outside. Not the best design, I know. There is a single hinge bolt of sorts on each side. I want to add more, but I can't find any of the same design. I want the same design because I know they will then fit in the moulded grooves on the edges of the door and the frame.

The longer part fits on the door, and its central section has a little triangular-section piece that rotates on a small spindle.
Does anyone recognise them and know where I can get more?
