I've been scouring LP101 and google for information on how to pick a lever lock, but i've only seen minimal information on exactly how a lever lock operates, and how one would go about picking it.
If someone could direct me to a site or a page on this board that explains these concepts better I would be apreciative. I'm mostly looking to start with older lever locks. For example: http://www.motherofpearl.com/jpgs/MORTICE%20LOCK.jpg
