Thanks for reaching out! Your mortise lock looks like it could be the 82-268B Multi-Point Mortise Lock. To determine if this is the right replacement, you'll need to remove the existing lock and carefully compare the dimensions. This will require removing the part of the frame covering the lock to access it.
