Does it fit marvin casement windows

Hello there!

Thank you for reaching out to us. Our 39-107FK looks very similar to what you have here. I wonder if yours is just an older version. To help us confirm if this part would work for you, can you show us a photo of your operator with the window open so that the arms that move the sash are fully visible? Once we can identify the operator, we can determine which handles are compatible with your assembly.
