Prototype Bavarian Version: The standard variant of the C III was developed from the C II. A total of 239 examples were built, which varied somewhat in their dimensions. For example, the third batch had a boiler diameter 30 mm greater than the others. The locomotives taken over by the Reichsbahn were to have been given the numbers 53 7871–7990. However these locomotives were retired by 1925. Several engines were sent to Belgium as WWI war reparations.
