Door lock deck

Hello there. This code is sometimes seen on the lock body used in the 82-249, 82-260, and 82-265 Mortise Locks, which all have different faceplates. Take a look at these mortise locks, compare their dimensions listed in the photos of their shop pages with your old lock, and let me know if one of them matches what you need. If not, we'll need photos of your actual mortise lock removed from the door to help further.
