Hello,

Unfortunately, I can't be sure of the hardware that your window uses since the hinge is not fully visible in your photos but the bracket of the operator reminds me of the Pella 39-176

Dimensions for 39-176

We've also related the Pella casement hinges that we carry on this page for you to review. Take a look and compare the specifications from our product pages to determine if one of them matches your original hinges. Thank you!
