The Chevrolet Master and Master Deluxe are American passenger vehicles manufactured by Chevrolet between 1933 and 1942 to replace the 1933 Eagle. It was the more expensive model in the Chevrolet range at this time, with the Mercury and Standard providing a cheaper and smaller range between 1933 and 1937. Starting with this generation, all GM cars shared a corporate appearance as a result of the Art and Color Section headed by Harley Earl. From 1940 a more expensive version based on the Master Deluxe was launched called the Special Deluxe. This was the last Chevrolet that was exported to Japan in knock-down kits and assembled at the company's factory in Osaka, Japan before the factory was appropriated by the Imperial Japanese Government. When Toyota decided to develop its own sedan called the Toyota AA, a locally manufactured Master was disassembled and examined to determine how Toyota should engineer its own cars. South African units were assembled at the General Motors operation in Port Elizabeth.
The Series CA Master replaced the 1933 Eagle midway through the model year when the 1933 Standard model (Series CC) was introduced. Several changes were made to the Eagle when the name was changed to Master. The easiest to identify is the post between the front door wing windows and the roll-down windows. On the Eagle the chrome divider between these two windows goes down as the window goes down, whereas on the Master this divider remains fixed and does not go down with the window.
