Thanks for writing in! Your casement window operator reminds me of the 39-387 Split-Arm Operator. The exact replacement for your operator is no longer available but I am confident this should work for the repair. To confirm, carefully look over the specifications and compare them.
The compatible hardware and accessories can be found tagged below.
