Thanks for reaching out! I believe you may be able to replace your existing operator with our 39-138 Single Arm Crank Operator and its opposite handed version, part 39-139. These are compatible with the 39-114L Crank Handle or the 39-205 Truth Folding Crank Handle.
Keep in mind, since these operators have a stainless steel roller at the end of the arm and you'll likely need to replace the window track as well. That said, the compatible track is the 39-520 13-1/2" Operator Track.
In regard to the window lock, take a look at the 38-005 Truth Hardware Locking Handle. Compare its dimensions and designs to your existing lock to confirm that this is the right replacement for your window.
