We carry the 39-020 operator, which looks to have a similar design but with a 9" arm. You might want to consider our 39-254E. This has a different style, so I'm not sure if it can work on your window, but it has a 7-1/2" long arm. It's also installed under the sill cover at the bottom of the window while yours is installed butted up to the sill cover. You might also need to install a new track our 39-533. I cannot guarantee it will work as a replacement, but we do not have a closer match.
