operator

Sounds like a job for SWISCO. We can help, we just need to see some photos of the operator in question. It's always best to take a photo of the part from a bird's eye view while the window is open so that we can see the full extension of the arm. If you're also able to get some measurements of the part, that would provide more help to us. 

Thanks for getting back to this! Ah, I'm afraid this operator is no longer made and is not available. Sorry that we can't be of more help, and many thanks for considering our business.
