Thanks for contacting us! Your casement window operator reminds me of an older version of the 39-264 Andersen Split Arm Crank. Since the based of the operator is much different from the base on yours, you may also need the 39-362 adapter plate to install it. Take a look over their dimensions and compare them to confirm.
