Looking for a replacement for this window crank opener for a skylight, as the interior gearing is stripped. Maybe Andersen, but not sure, and doesn't match anything I'm seeing online.

You've stumped me on this one. This is very unusual, especially with that spring attachment. Check to see if you can find any name on the operator, glass or the window itself to determine the manufacturer. That may be our only hope!
