Corroded casement window

Thanks for reaching out to us! I agree that our 39-253LB operator resembles what you have here. Take note that this uses the 39-529 track slider (sold separately) so you'll want to make sure your operator does as well. 

The part in your first photo is familiar though. Is there more to it? Would it be possible for us to see a photo of the rest of the assembly? 

As for the plate in your second photo, the 38-278 is the closest I could find but I can't promise it will work since it differs from the original. Take a look and see what you think. 

Ahh, I see now! For the stud bracket, see the 39-545 and 39-546. I'm afraid I couldn't cross-reference the numbers on the lock plate, however. The 38-278 remains our best option, unfortunately. I am very sorry that we can't offer a suitable replacement. 

That's very kind of you to say, thank you! I'm just happy I could help. Good luck with the repair, you know where to find me if you need anything else!
