Hello, thank you for posting,
For new handles, please review the 39-286 style. We do carry the 39-154 cover as well, but it appears the crank operator in your first picture may be stripped. If this is the case, you will need a whole new operator.
To further identify the style you have, we will need to see the window open where we can see the operators arm. From there we can determine the operator your window uses.
Compare dimensions and let us know what you think!
Thank you for the additional pictures,
Your operator resembles either the 39-094 and 39-095 or the 39-150 and 39-151 styles. The main difference is the length of the arm. Please review both and the orientation to determine the best fit. Let us know what you think and if you have any additional questions!
