Exceptional quality late 18th century Georgian mahogany stick barometer by one of London's best-known instrument makers of the era, William Cary. This barometer has the highly desirable swan's neck pediment at the top and features hand-engraved silvered plates with a sliding Vernier scale. Wonderful honest wear to the silvered plates from the Vernier scale being adjusted up and down over many years of use. I believe this is quite an early example of Cary's work, as this particular version requires the user to unlock the door to adjust the vernier slide. Later examples have a separate knob on the outside to adjust the knob. The door is currently unlocked and there is no key. This barometer is sold as found, without its mercury, although the glass tube appears to be intact, albeit cloudy.
