Window crank for old wooden window

Hello there. Can you send us photos of your existing hardware, including the window operator? A bird's eye view, either with the operator removed from the window or at least with the window open, would suffice. We'll do our best to help from there.

Thanks for getting back to me. This looks like a Pella setup. I believe the handle is our 39-109B, which can work with either the 39-096 or 39-176 Pella Casement window operators. Unfortunately I cannot tell which one you have without seeing the mechanism in its entirety. When possible I suggest you access the operator so you can compare with the diagrams below to see if either matches what you have. See what you find.
