Knob for sunroom window does not work

Question

One of our sunroom windows no longer closes. We had it so it was permanently shut, but it was accidentally reopened and now does not close. Hoping to just replace that knob. Unfortunately we don't have any information on the brand of the window.

According to a local window distributor, our sunroom windows are very good quality so we don't want to replace them.

I have attached multiple photos as reference. If the replacement part is available, we will be able to install it.

Thanks for your help!

Thanks for posting. Please give me the distance between the installation holes, if you can. We would also like to see it removed from the window that so that we can get a good look at the internal gear and link arm. This information will allow us to find a good match. Also take a look at our video below, that may help.
