John Bliss & Company, of New York City, sold navigation equipment, including barometers, from the mid-19th century until going out of business in the mid-1950s. This one, bearing the Bliss imprint, was made in France.
We believe this handsome, holosteric barometer dates to the early 1900s. It is in good working condition, with a brass case, and measures 4 7/8 inches across the face and is 2 inches deep, front to back.
This style was popular among shipmasters because of its portability. Ship captains would carry their sextants and other navigation equipment with them when they boarded ship.
Have your own weather station. Set the barometer to the barometric pressure in your area and keep track of changes day to day.
