Vintage unique set of 2 Sargent Locks-Both can be rekeyed

These are 2 vintage Sargent Locks. One has a key that works. The other works, is open and just missing the key. The one with the key missing says M ss on the bottom. The lock with the key has no ititials or they are worn off. I am not a collector so please email any questions. Both can be rekeyed.
