Hey there,

Your window crank appears to be the 39-015 Roto Gear Window Crank. To confirm that this is the right replacement match, you'll need to compare the measurement as shown on the diagram below.

You may also need the 39-114L or 39-205 (folding) crank handles to replace the handles and the 39-170 Window Sash Brackets to replace the hooks.
