Hello, Your handle set reminds me of the 82-009A with a clamp-style latch depending on how the specifications below compare to yours. This handle set does not come with an external key lock but it can be used with the 82-306 keyed exterior pull. Take a look and thanks for posting! Alternate image for 82-009A

These handles actually do not use a separate mortise lock since the 82-009A uses a clap-style latch attached to the internal handle as shown below. The latch is what would engage with the frame to lock the door, which appears to be how your original hardware was designed. Alternate image for 82-009A
