In 1950 the Alvis TA 21 was launched with new chassis and a 6-cylinder 2993cc engine. Mulliner and Tickford provided most of the bodies for these cars, but as both companies fell into the ownership of rivals, Alvis found it difficult to cloth its chassis. Hermann Graber bought an Alvis TA 21 chassis and presented this at the 1951 Geneva Salon to much acclaim. Further work on Alvis followed, and in 1955 he presented a lovely coupe to the Paris Salon and Alvis did a deal to produce this car locally. The bus company Willowbrook were contracted to produce this Paris car as the Alvis TC108G, but its high price saw only 16 sold. Herman Graber continued his own work selling more than 100 Alvis Grabers as well as Graber bodied Aston Martins, Bentleys and Lagondas. Mulliner took over Willowbrook and plagiarised the Graber Special to produce the much cheaper and more spacious TD 21 - TF 21 models.
