Casement window operator

A quick learner from Port Ewen, NY says:
Unable to determine window manufacturer. I need the Operator for window (34x44) opening left. This is a picture of operator on adjacent right window. Unclear which operator I should purchase. Any help would be appreciated. Thank you.

Hey there! Your operator reminds me of our 39-220B, it's opposite side is part 39-221B. Take a look at the dimensions and compare them to your existing hardware to confirm that it is the right fit. I am confident this is the operator you'll need.

The bracket being used to connect the operator to the window with the 39-220B is our part 39-545 (its opposite is 39-546). The compatible cover is part 39-375 (its opposite is 39-376). The cover and handle kit comes in an assortment of different colors.
