Begin by taking a look at the 39-027E Window Crank, I believe that could be a match for your operator. Be sure to compare the dimensions of your operator (arm length specifaclly) to the 39-027E. We also carry the longer operator, the 39-013 Casement Window Crank, measuring 13 1/2".

Take a look at the 39-027E and 39-013 and compare it to your original.
