part of 1946. Despite this, Alvis carried out war production on aircraft engines (as sub-contractor of Rolls-Royce Limited) and other aircraft equipment in its shadow factories. Post war Car production resumed with a four-cylinder model, the TA 14, based on the pre-war 12/70. A solid, reliable and attractive car, the TA 14 fitted well the mood of sober austerity in post-war Britain, but much of the magic attaching to the powerful and sporting pre-war models had gone and life was not easy for a specialist car manufacturer. Not only had Alvis lost their car factory but many of the pre-war coachbuilders had not survived either and those that had were quickly acquired by other manufacturers. The post-war history of Alvis was dominated by the quest for reliable and reasonably priced coachwork. 1950s Smith-Clarke retired in 1950 and Dunn took over as chief engineer. Before retiring Smith-Clarke came up with the Alvis 3L3, TA21 prototype in 1947, TA14 body with a six-cylinder 3-litre engine, after retiring he used the prototype Alvis 3L3 as his personal car. In 1950 a new chassis based on the TA14 and six-cylinder 3–litre engine was announced and this highly successful engine became the basis of all Alvis models until production ceased in 1967. Saloon bodies for the TA 21, as the new model was called, again came from Mulliners of Birmingham as they had for the TA 14, with Tickford producing the dropheads. With Mulliners committing themselves in October 1954 to supply only Standard Triumph, which purchased Mulliners in 1958, and Tickford being acquired by David Brown, owner of Aston Martin Lagonda in late 1955, it was becoming clear that new arrangements would have to be made. Some of the most original and beautiful designs on the 3 Litre chassis were being produced by master coachbuilder Carrosserie Herman Graber of Switzerland. These often one-off–designed cars are highly sought after today. Graber had begun to use TA 14 chassis soon after the war, building three Tropic coupés which were much admired. When the Three Litre chassis was introduced, his bodies displayed at the Geneva Motor Shows in 1951 and 1952 attracted sufficient interest for Graber to set up a standing order of 30 chassis per year. Swiss-built Graber coupés were displayed on the Alvis stand at both Paris and London Motor Shows in October 1955. With a licence in place, from late 1955 all Alvis bodies became
