American Seal Lock Company Antique Lock
This is a very rare and hard to find lock. The lock does come with the key and yes, it does work. It is a little rough, looks like it could use a good cleaning and/or oiling but the lock will lock and unlock. The face looks like it was covered in shalac at one point and it has worn off (please see pics). We do not believe this is suppossed to be here but it can be up to you if you want to clean it off or not. - eBay (6 Dec 2010)
