Hi there Russ.

Thanks for reaching out to us. We have the 40-194 mortise lock but I don't know if it will be compatible with your existing handle set. The only other thing that comes to mind is the 40-049 handle set though the lock is not sold separately. Have a look at the specifications for these parts and see what you think.
