The Soviet cameras followed the pattern of the Leica II, while most of the Asian cameras included the slow-speed feature. After 1940, with the introduction of the Leica IIIc, the upper body was die cast rather than stamped and the visual appearance of the camera changed with a more prominent shutter-crate around the lens mount - this was not covered with leather as in the previous models. The post 1932 Leica II and Leica III cameras were differentiated by the latter having a 'slow speed dial' on the front of the camera to the left of the lens mount. This camera's features are the basis for defining a Leica copy. In 1930, an improved model with interchangeable lens was introduced, followed a year later by the fully developed Leica II with standardized film to lens flange distance, and in 1932 the basic Leica Standard the Leica concept was established. Once started, the Leica production volume doubled each year in 1929, some 16.000 cameras were produced. The design was carried out by Oskar Barnack, beginning in 1913 by building a camera for 24×36 mm negatives that by now is called the Ur-Leica but Ernst Leitz did not decide to manufacture it until 1924.
