Eagle 30 year old casement window open and close mechanism( brown)

We may have what you need, but I'll need photos of the operators in question before I can recommend anything. Truth has made many, many different kinds.

Seeing it out of the window would be the most helpful, but at the very least I need to see as much of the part as possible in one shot.

We're getting there. I'm afraid I also need to see the link arm(s) connected to this gear box that push and pull the window. Can you open the window so we might also see those arms? From there I should be able to ID the operator. 

That is a huge help, thanks! Your operator looks close in design to our 39-035 and 39-036. I think yours is just an older style. Look these parts over and let me know if you agree.

These photos also focus on your top and bottom hinges. I'm not sure if you need those, too, but see our 36-048 hinge pair. These should work well for your window as long as you replace the top and bottom at the same time/

The 39-035 doesn't go on the top of the window. The hinge does, though, which is why our 36-048 comes in a pair. The video I posted shows you how these are installed.

Not through me specifically, but all orders can be placed from our site at your convenience.

Thank you, you as well!
