Corona
Evans decided to rebrand his soft drinks and chose the name Corona. A logo was devised consisting of seven wire topped bottles fanned to represent a crown over the new name (corona is Latin for crown). The brand was extremely successful and expanded across South Wales and at its peak, the company had 82 distribution depots and five factories, at Porth, Tredegar, Pengam, Maesteg and Bridgend. Although a common and popular sight throughout Wales, the horse-drawn wagons were phased out during the early 1930s and replaced by a fleet of motor vehicles. These vehicles, recognizable by their red and gold livery and Corona logo, were serviced and repaired by the company's own engineering shop attached to the Porth factory. By 1934 the Porth depot had 74 vehicles and three years later that number had risen to 200. In 1934, William Evans died and the role of chairman and managing director was taken over by his brother Frank, a role he would maintain until 1940. Under Frank Evans' management the company continued to grow and by the end of the decade the factories of Wales were producing 170 million bottles a year. With the outbreak of war in 1939, many of Thomas and Evans motor vehicles were commandeered by the government for war service. This, along with petrol rationing, saw a brief reintroduction of the horse and wagon delivery service.
