Ooops...maybe I lie. The door leaning against my house, I can see from my office window, was made in the 1890's and the french door leading into the office was made in the 1930s. The door knob was manufactured sometime between 1895 and 1898 and although I can't see it from here, my bathtub is circa 1902 or 03. I guess they are still not as old as the barometer, but at least the doors were manufactured here.
