Bears the legends “Fisherman’s Aneroid Barometer” and “As Issued by the Royal National Life Boat Institution,” and inscribed “Negretti & Zambra, London” and “No. 15204.” Blued-steel indicator with gilt brass telltale, heavy bevelled plate glass with centre-mounted knurled and gilded brass setting wheel.

It is understood that manufacture of these instruments commenced in the last quarter of the 19th Century, and they were made available to Merchant Navy masters and fishing vessels alike. Although manufactured in reasonable numbers, relatively few of these survive especially in this very good state. The fisherman’s barometer, having been cleaned, checked and calibrated, remains in excellent original condition in all respects.
Negretti & Zambra, founded in 1850 as makers of scientific instruments, were the most prolific and leading makers of all types of barometers during the second half of the 19th century. The partnership exhibited at the Great Exhibition at the Crystal Palace in 1851 and won a Prize Medal. Negretti & Zambra held the appointment of instrument-makers to Her Majesty Queen Victoria, Prince Albert and Edward VII, the Royal Observatory and the British Admiralty (see Banfield, Edwin, Barometer Makers and Retailers, 1660-1900).
