A French made barograph of gilt brass and thick beveled glass, of unusually small size. The small drum contains a 8 day clock and has a seven day chart fixed to it. The stack of bellows activate the arm with the ink knob attached, and the barometric pressure is recorded on the paper chart as a continuous line. A year supply of charts is included but more are available. Fully overhauled and fully working.
