Truth casement openers & hinges
We should be able to help with this project, but I can't quite make out your operator in these photos. Your tape measure in the last photo is obscuring some of the most important details. Can you take a picture at that same angle but without the tape measure?
In the meantime, see the 39-013 and 39-14. These may be what you need, but review their design and see what you think. These are compatible with the 39-114L handle.
For the hinges, I recommend our 36-048. These won't be identical to the originals but as long as your base track is 10" and as long as you replace the top and bottom at the same time then it should work perfectly fine.
