Thanks for posting! I am confident that we can supply you with the replacement casement operator you'll need, however I'll need to see a photo of the entire operator to confirm.

I am specifically looking to see a photo of the body of the operator as well as a photo of the arm(s) and how the operator attaches to the bottom of the window.

Please let me know if you have any questions.

Thanks for the photos. Your operator looks like it could be the 39-146 and its opposite handed version part 39-147. Carefully review and compare the dimensions to your existing operator to determine if this is the correct replacement. The compatible crank handle is part 39-286.
