Not sure what is needed anymore
Hey there,
Thanks for writing in! It sounds like there is an issue with the internal mortise lock. To determine if there is a replacement we can supply you with, I'll need to see the lock removed from the door. I cannot make any guarantees but I am happy to review the hardware to confirm.
Please let me know if you have any questions in the meantime.
Thanks for the photos. I'm sorry to say that we would not be able to supply you with a replacement for the mortise lock you have here. The closest match we have to your mortise lock is our 82-259, however I do not believe it would be compatible with your handle set and it has 9-7/8" installation hole centers.
I do apologize that we cannot supply you with a replacement for your existing hardware.
Please let me know if you have any questions.
