Hi there!
Could you remove your window operator and show us the arm? That will help us narrow down our options.
Thank you!

I have the same configuration and need the replacement gear arm for my window. Do you have the part at SWISCO?

Have a look at the 39-414 operator used for top venting windows. This is normally used for top venting windows in trailers and RVs. Review the specifications and see how they match up with yours.
