This is an aneroid pocket barometer with a revolving altimeter scale measuring zero to 8,000 feet.
Dating to the last quarter of the 19th century it's signed 'DOLLOND LONDON' on the dial and is also compensated for temperature.
The case is made of brass with a dark gunmetal finish and is in good condition with only some minor rubbing on the reverse.
It comes with its original Moroccan leather dark brown case
with purple and blue silk-velvet interior, which is also in good
condition with a sound hinge and catch, although the button is a later
replacement.
The barometric scale reads from 23 to 31 inches and all the
lettering and numbers are etched into the clean silvered dial.
A fine example of a Dollond pocket barometer, it measures 50mm
diameter x 17mm depth, and is in full working order.
Please study the photos as they are part of the description, and I will be happy to answer any questions if I can.
