Travel Compendium by Negretti & Zambra
Travel Compendium by Negretti & Zambra. A lovely pocket barometer and compass travel compendium by Negretti & Zambra. Numbered 10055 the barometer is in excellent condition but does require some expert attention as does not work with a pressure test. The compass also is in excellent condition and full working order. The case is in nice condition inside and our but has suffered some damage so is fragile.
Enrico Negretti and Joseph Zambra started their company in 1850, which was run by them and their descendants until well after WWII. They had shops firstly in Regent Street and later on at Holborn Viaduct. The company was highly successful from the start, winning a medal at the Great Exhibition in 1851 and counting among their customers the Astronomer Royal, Prince Albert, the Royal Observatory and Admiral Robert Fitzroy. In the early days they specialised in barometers and thermometers, particularly those required for taking deep sea and atmospheric measurements, which until they came on the scene were terribly unreliable. Later on they increased their range to include telescopes, gun sights, theodolites and similar optical instruments. During World War II, N&Z expanded substantially to meet the demand for instruments for war planes in particular. Their instruments were also produced under license to supply the USAAF.
