Crosley's first foray in the automotive world took place in 1939. Their first range of models are collectively known as the Series cars. These cars were never given official model names, as they were simply known as Crosleys. The first four years of Crosley production were given 'Series' names. 1939 offerings were known as the Series (C)1A, 1940 offerings were known as (C)2A, 1941 offerings were known as Series CB41, and 1942 offerings were known as Series CB42. These cars were built in a wide range of body styles that included convertible, sedan, station wagon, panel delivery, and pickup versions. Power came from a flat twin engine that was available with a displacement of 575cc, which sent power to the rear wheels via a 3 speed manual transmission. Production of the Crosley Series cars ended in 1942 due to WW2. Post-war, Crosley continued automotive production with the CC Four.
