I'm afraid I don't recognize this operator. That link arm is huge! We don't have anything quite that size. Could you confirm the diameter of that hole? I can't quite make it out from just a tape measurer. 

The largest hole size we have for any of our awning window operators is 3/8", like for our 39-074, 39-193, and 39-419. I can't say if any of these will work, but if the link arm hole is the same size then they may be worth considering. You just need to make sure the screw hole pattern is the same. It's different on each one I just mentioned.
