Thanks for reaching out to us! Your window operator appears to be made by Truth. If I am correct, you'll need the 39-205 Truth Folding Crank Handle to replace this crank.

You'll need to measure the diameter of the opening on the handle and/or the spline on the operator to confirm that the measurement is 11/32". Take a look at the diagram from the 39-114L Crank Handle for reference.
