Semco biparting door

Hello, thank you for posting,

Unfortunately we are not able to supply an internal mortise lock that will be compatible with your door. I apologize that we cannot assist with this repair. 

If you also need a new handle set, we do not have an exact replacement, but take a look at the 82-093 to see how it compares to your original. 

Please let us know if you have any additional questions.
