Pella window replacement lever

Thanks for reaching out to us. We unfortunately don't sell a Pella brand lock that matches this. To be honest, this doesn't look like a Pella part from what I see. Can you confirm that? Is it also possible to see both the handle and plate removed from the frame?

Thanks for verifying that! Were you also able to remove the lock and base plate from the window for me to review? At this stage, I don't recognize your lock and can't make a recommendation until I can see the full assembly without obstruction.
