The Krupp 7.5 cm Model 1903 was a field gun used by a number of European armies in both World War I and World War II. The Model 1903 was a "stock gun" from Krupp that could be supplied to customers on short notice with minor alterations to suit the customers needs. The Model 1903 was also bought by Denmark and the Netherlands and used in World War II. The Model 1903 also formed the basis for the Type 38 75 mm Field Gun used by Japan. In Danish service it was known as the 03 L/30 and doesn't appear to have been modified in any significant way before World War II.
