This is a good used flush mount type antique interior door lock set with privacy lock marked "ENTERPRISE" on the catch. It is all cast metal with white porcelain knobs that are well attached to cast metal flanges. All the parts needed are included except the wood screws. This is one of the easiest lock sets to mount to your doors, just one through hole in the door needed along with screws for mounting, no notching or mortises needed. The keeper is 3.25 x 4.12" and is reversible. There is a trigger activated dead bolt type locking mechanism on the keeper, but no key. The key hole escutcheon seems to be made of lead, and needs painted if you decide to use it, it is original to this set. This set is in good shape, no rust, works fine, could use a repaint, as some of the door paint is on the flange and keeper in a few areas. We have others that are similar to this one, flush mount type, with white handles, but minor differences in castings, all from the same house. We also have original doors these fit on originally. All listed separately.
