Thanks for posting. I'm afraid I am uncertain if we have a replacement for this lockset. Can you show us a clear picture of the side-profile of this mortise lock removed from the door? In the time being, I am forwarding this discussion to one of my senior colleagues who specializes in these kinds of lock sets. We'll do our best to determine if we have a possible replacement for you. Many thanks.

Hello there! I am afraid I'm unsure if we can supply you with the exact same handle set. I believe our closest match is our 82-400. Compare it to your old hardware to see if it matches up with what you need.
