do you have these- casement and crank?

The design of this operator base is a little different than the parts we carry. We may still be able to help, but I'd like a better idea of what you have here, if possible. Would you be able to open the window as far as it can go and show me a clear picture of the arms? Seeing the operator removed from the window would actually be the most ideal, but at the very least I need to see as much of the complete mechanism as possible, even if it's still installed. Thanks!
