(casement = side opening)
These side-hinged windows have a catch that you turn to open or close. The catch goes out with the window.
In the bottom corners of the frame there is usually a brass double sliding arrangement with a thumb-screw to clamp the window in the open position. These slides are no longer available.
Should this type of window have fly screens they will generally be of a roll-up-and-down variety (like a holland blind) running in a guide rail either side of the frame. Or they might be slide-up-and-down or slide-side-to-side screens.
Crittal windows are generally not suitable to convert to winders.
