Casement window
Thanks for reaching out! The window operator pictured here reminds me of the 38-095 Andersen Straight Arm Operator. You'll need to carefully compare the dimensions to confirm that this is the right fit for the repair.
This operator is sold with the compatible track but the 39-286 Casement Window Handle is sold separately. You'll find the opposite handed version of this operator tagged below.
I believe you may be able to use the 36-048 2-Bar Hinge Set. To determine if this is the right replacement, carefully look over the dimensions below and compare them.
This set can be used to replace the top and bottom hinge for right and left handed applications. It is advised to replace both the top and bottom hinge to ensure they will be a match.
