Casement Operator Replacement for an MI Window model 9770

Greetings from SWISCO. I see you mentioned that the operator you are showing is right handed. However, when I look at your part, I see that it matches closely with our 39-220 left hand sill mount operator. Take a look and see if you agree. If not, look at our right handed version, our 39-221. See if either one of these parts will work for you.
