Unfortunately, we don't sell a mortise lock that matches the dimensions given. Based on how old the door appears to be, there is a good chance that the part you need isn't made anymore and hasn't been for a long time.

You may want to consider a new surface-mounted handle set like our 82-005. This is nice because it comes with its own mortise built into the handle itself, forgoing the need to interact with anything inside the door. The catch is that it will be necessary to drill new holes for it to install. Check it out and see what you think.
