Formed by William Simms and Edward Troughton in 1826, Troughton & Simms instruments were highly regarded for their accuracy and reliability, earning the company a prominent place in the scientific community.
 
This late Victorian aneroid pocket barometer made by Troughton & Simms has a barometric scale ranging from 28 to 31 inches, with a rotating altimeter scale from zero to 3,000 feet.

Engraved 'Troughton & Simms LONDON 818', on the silvered dial which has some light spotting (see photos), the brass case retains almost all of the original gilding, with only some minor tarnishing on the edges and is dent free.

The company was renamed Troughton and Simms Ltd, after the death of William Simms son James in 1915, showing this barometer was likely made in the last quarter of the 19th century.

Larger than usual pocket barometers, measuring 73mm diameter by 28mm deep and weighing just under 300 grams, it comes in a leather case with shoulder strap, which is also in good condition with all stitching intact.

Please study the photos as they are part of the description, and I will be happy to answer any questions if I can.
