Zenith Carburetter Company was a British company making carburettors. In 1955 they joined with their major pre-war rival Solex Carburettors and over time the Zenith brand name fell into disuse. The rights to the Zenith designs were owned by Solex UK (a daughter company of Solex in France). While better known for their much later products, Zeniths were standard equipment on some very early, brass era automobiles, including the Scripps-Booth.
