Hello there. I am afraid that your operator is no longer available. We did at one time have a replacement for this setup, but to add insult to injury the manufacture discontinued that operator also. If your operator is in working order however, you might just need to install the new Roto base: see our 39-248. Hopefully that is all you need to repair your window. On the locking handles take a look at the 38-138 or the 38-139 with the longer fork. If your operator is not in good working order let me know--I can try and see if we have something else that might work.
