Help to identify part

Thanks for reaching out to us. I'm afraid I don't know what this lock set is. We sell a handful of sets that are similar, but as you are looking for an exact match we will need more precise data to go off of before we make a suggestion.

To start, I'll need a clear picture of the interior handle as well as the internal mortise lock, preferably removed from the door. I will also need all relevant dimensions written out and as precise as you can manage. Finally, knowing who made the door to begin with would be a huge help.

Once I have that information I can check our inventory to see if we have a good match.
