Thanks for writing in. The window operator you have here appears to be a Roto brand operator like the 39-341 and 39-342 Roto Dual Arm Casement Window Operators. This is most often used with the 39-232 Roto Folding Crank Handle.

To confirm that this is the right replacement, you'll need to confirm the spline measurement on the operator. This handle will fit an 11/32" spline.

The handle in the first photo is the 39-230. This is used for operator that have a hex gear bore measuring 5/16".
