A good and early barograph in a mahogany case.
Very fine mechanism of lacquered brass. The substantial mechanism raised on four brass pillars. The swinging gate arm, nicely formed counter weight. On the ground plate remains of red ink. Rare five unusual thick bellows, see fig. 98 in “Barometers Aneroid and Barographs’ by Banfield for an engraving of Brequet’s barograph. Good formed winding key. The steady ticking movement has a brass cover and keeps staying on the platform when removing the drum.
Signed on the brass plaque:
Overall a beautifull instrument in very good and working condition.
Dimensions: 27,5 cm wide, 14 cm deep and 16,5 cm high.
