i have to hang a few 5 panel doors for a customer and she wants the old mortice style locks.i really don't want to mortice the doors to a 4-1/2" depth.i'm looking for a lockset that would look like the mortice set with the rectangular plate and glass knobs, but i would only have to drill a 2-1/8" hole like the newer locksets.i tried searching the internet but no luck.does such an animal exist?thanks.
