Hello! Your exact operator style is no longer made, but we sell the modern 39-013 and 39-014 that should work just as well in this application. These are compatible with the 39-114L handle.
It also looks like you need a new hinge. Our 36-048 may work in this case, but only if the base track is the same size at 1", and only if you replace both at the same time.
Lastly, you mentioned a lock, but I don't see it in these photos. Would you have a reference I can review? Seeing it removed from the window would be ideal, to ensure that no important details are missing.
Otherwise, please review the parts I mentioned and let me know if you had any questions.
Thanks! I'm very familiar with this lock. Like your operator, the exact style is obsolete, but Truth made the 38-097 and 38-098 to replace it. Just note that the new style won't be compatible with the old keepers, so you will also need the 38-079.
The operators I mentioned before remain my top suggestions. Your next step is to review the hardware I've recommended to see how well they compare.
