This would be a great addition to a restoration project, as it comes with almost all hardware required. There might be a set screw needed for the interior doorknob, but otherwise this is a complete set. There is some masking tape residue on the exterior doorknob escutcheon which can be easily removed, but we've left that for the new owner to decide what method they'd like to use for the removal process. Feel free to message me with any questions.
This item is made of brass.
