Hello, thank you for posting,
Unfortunately we do not carry an exact match for this operator. Your operator is similar to the 39-044, however it no longer comes with the 7" arm like you show in your photos. We cannot guarantee they will be a direct fit or function, but start by taking a look at the 39-466 and 39-467 operators with the 7-1/2" arm. It is not the same style as your operator, but could work for your window as a replacement.
Also you might need to replace the track on your window because of the break in. Take a look at the operator along with the handle 39-114L and the different styles of tracks. The 39-504 under mount and the 39-520 face mount. These tracks might have to cut depending on the width of the window. Also look at the related videos.
Let us know what you think!
