From my Barometer collection: Here we have an Antique, NEGRETTI & ZAMBRA , Gentleman’s Gilt Brass Compensated Aneroid Pocket Barometer Altimeter, 1800’s! . Was a company that produced scientific (philosophical) and optical instruments and also operated a photographic studio based in London, England. Henry Negretti (18181879) and Joseph Zambra (18221897) formed a partnership in 1850, thereby founding the firm which would eventually be appointed opticians and scientific instrument makers to Her Majesty Queen Victoria, Prince Albert and King Edward VII, the Royal Observatory and the British Admiralty. (Both Negretti and Zambra were born in Italy). Their company were well known for manufacturing high quality instruments such as barometers, sextants, microscopes, telescopes, and photographic equipment. The dial is marked STORMY RAIN CHANGE FAIR VERY DRY. LONDON 26943 (the serial number). This instrument is in Excellent’used’ condition. The gilt brass cased barometer is in working order and has been verified by use of the’plastic bag’ test. The brass case shows very little wear with a nice patina. The silvered dial has a very nice scroll-work etching in the lower half and has a clean appearance. No nicks, chips or cracks in the beveled-edge crystal. The revolving outside altimeter ring works as it should. The top crown and bow ring are in very good condition. It comes in 1/2 of the original Moroccan Red Leather case which is lined with a fine green felt. Nice complete and working barometer!! THAT MANY SELLERS TRY TO MARKET AS AN ANTIQUE.
