Hi- thanks for posting!
Do you just need the handle replaced or the crank itself? If you need the entire mechanism replaced, we will need to see a top down photo of it. Open the window as far as it will go and take a birds eye view photo. Get back to me if you have any questions.
Thank you for getting back to us with some bird's eye view photos! I can't tell the length of your operator's arm from the pictures, but try taking a look at our 39-028E and our 39-014 .
The 39-028E has an arm length of 9-1/2'' and the 39-014 has a longer arm measuring 13-1/2''. Let us know if you think one of these matches the measurements of your operator.
