Chrysler had introduced the Windsor as a full-size range with its 1939 models and this was re-styled annually until 1942 when WW2 halted production. The Windsor was built on a 122.5-inch wheelbase and powered by an L-head inline six. The 1946 Windsors relied heavily on the 1942 versions, but still achieved more than 60 per cent of Chrysler sales. To celebrate Chrysler's 25 years in production a new 'boxy' style was brought in in 1949. New Chairman KT Keller oversaw the unadventurous 'Keller look' for this new body which had versions wearing 'DeSoto', 'Dodge', and 'Plymouth' badges. In 1951 the Windsor became Chrysler's entry level car (although Plymouth models were lower priced) when the 'Royal' was dropped. The Windsor and Windsor Deluxe shared the 125.5 inch wheelbase of DeSoto models. For 1953-54 Chrysler gave new bodies to its models with one-piece windscreens, and in 1955 the Virgil Exner 'Forward Look' appeared on the Windsors.
