I have an old Stillwater Casement where part of the mechanism broke off and I need to replace the mechanism. The window was installed between 1973 and 1976. There are no marking or stampings to identify what the brand of mechanism is. Thank you. Nancy

This is a very old window operator. I don't think this exact model is made anymore, but there are a few details obscured that we need to see. It's best if you just remove the operator from the window and show us one clear shot of the entire thing, from a top-down angle. That's typically what this service requires, and for a part as old as this I think it's necessary.
Once we have that, we can check our inventory for a match.
