I want to know the answer to the following question:
Which company redesigned the rapid fire 2 cm FlaK 30?
All the background I'm provided with is that "Rheinmetall in Germany developed an automatic 20 mm in the 1920s and Oerlikon in Switzerland had acquired the patent to an automatic 20 mm gun designed in Germany during World War I. Germany introduced the rapid-fire 2 cm FlaK 30 and later in the decade it was redesigned by Mauser-Werke and became the 2 cm FlaK 38.". Is that enough to answer the question?
