Antique Holosteric Barometer & Celsius Thermometer. Original carrying leather velvet case with shoulder strap. Paul Naudet – PNHB. Unusual to see one of these “paired” with a Celsius Thermometer. Thermometers semi circle – arc – are rare to their own to see! I put this into the freezer to get the mercury to go down, it did, I do not know how to adjust or calibrate either the barometer or thermometer. This is an extremely old example of PNHB Paul Naquet, France precision instruments. Look at all photos closely.
