Back in March I located the entire doorknob/lock/latch from an old schoolhouse. Original thread here:

Today I took the latch set to the local museum that has the old photos of the school and donated it to them to go with the photos. They seemed pleased to accept it, especially after I explained that I recovered it with written permission from the timber company that owns the land. I even got some leads for future hunts.
