Window hinge and operator sets needed what do I have ?

Hello, thank you for posting,

To further review, we will need to see pictures of the operators and hinges. The window sash will need to be opened where we can see clear views of the arm attachments and base. From there we can get a better idea of which style your window uses for a possible replacement option. Thank you! 

Thank you,

Once we can see the window open, we can further review to determine the style needed. Please also provide a clear picture of how the operator arm connects to the window sash. Thank you!
