I think you should consider our 82-218 mortise lock. This looks very similar to your original, but look it over and let me know if you agree.

Hello Tom
Thanks for taking time to answer my inquiry. Yes! The 82-218 looks like a match. I will order five of them! One more thing... Is it typical, by the time the lock is shot that the latch (on the door frame) and the lever (on the handle) need replacing also?

Not necessarily. My experience has always been t hat the spring inside the mortise fails way, way sooner than the handle itself.

Now, if the handle continued to see use after the spring had failed, then there may have been undue strain on the thumb lever that can lead to it bending or breaking. But if it looks to be in good condition at a glance then I see no reason why you can't reuse it.

Thanks for considering us and please let me know if you had a follow-up question.
