Hi, I was wondering if anyone would be able to give me some info on an old lock I have aquired. It say 12 on the top, Four Brass Levers, USN, Genuine Solid Brass. It has a little “door” where you can put the key. On the back it says JAS. Morgan & Sons under that it says Locksmith, and then above a small hole it says Drain. Thanks 🙂
