These are 7 antique skeleton keys. One key is marked LOCKWOOD, one is marked PENN and one is marked CORBIN. The other 4 do not have any makers marks on them. All of the keys measure 2-3/4 inches long except for one. It is just a little shorter. The keys do have an age patina and some have a little rust. They have not been cleaned or polished. Please let me know if you have any questions. Thanks for stopping by.
