Reg'd US Mail Lock

Here are some photos of an antique Registered US Mail Lock.

The special feature of these locks is that they have a built in counter that records every time the lock is opened.

I have a couple of these locks and it seems that the keys are the same for all the locks, althought it could be that I have a master key. I have another key that only opens one of the locks, so anything is possible.
