Zenith Carburetters was a British company making carburetors. In 1955 they joined with their major pre-war rival Solex Carburetters and over time the Zenith brand name fell into disuse. The rights to the Zenith designs was owned by Solex UK (a daughter company of Solex in France). Solex existed until 1986.
The big products of Zenith were the Zenith-Stromberg (used in MGs, early Saab 99, some 1960s Volvo 140's, and 1960s Triumphs, for instance the Triumph Spitfire) and Zenith IV carburetors.
