Nah, that's some fine patina. Just clear coat it and call it done.
In the days before A/C screened porches were used for everything. Most stayed on the porch until the house had cooled from the days heat. Remember sleeping out there when I was a kid,sorta like camping out. Always wanted one of those old farm houses that the porches went completely around the house.
